Stem Cell and Biobanking

Stem cell therapy is used to treat or prevent diseases by using stem cells. It has potential in a wide range of territories of potential and restorative examination. This treatment is by and large used to supplant or repair harmed cells or tissues. It additionally helps in transplanting immature microorganisms or giving medications those objective undifferentiated organisms as of now in the body. Undeveloped cell treatment is a rising innovation; the recovery of body part is not really another idea.

Stem cell transplantation, sometimes referred to as bone marrow transplant, is a procedure that replaces unhealthy blood-forming cells with healthy cells. Stem cell transplants commonly are used to treat Leukemia and lymphoma, cancers that affect the blood and lymphatic system.

Cell signaling mediated by morphogens is essential to coordinate growth and patterning, two key processes that govern the formation of a complex multi-cellular organism. During growth and patterning, cells are specified by both quantitative and directional information. While quantitative information regulates cell proliferation and differentiation, directional information is conveyed in the form of cell polarities instructed by local and global cues.

Epigenetics is the study of potentially heritable changes in gene expression (active versus inactive genes) that does not involve changes to the underlying DNA sequence — a change in phenotype without a change in genotype — which in turn affects how cells read the genes. Epigenetic change is a regular and natural occurrence but can also be influenced by several factors including age, the environment/lifestyle, and disease state. Epigenetic modifications can manifest as commonly as the manner in which cells terminally differentiate to end up as skin cells, liver cells, brain cells, etc. Or, epigenetic change can have more damaging effects that can result in diseases like cancer. 

Embryonic stem (ES) cells are cells derived from the early embryo that can be propagated indefinitely in the primitive undifferentiated state while remaining pluripotent; they share these properties with embryonic germ (EG) cells. Candidate Embryonic stem and embryonic germ cell lines from the human blastocyst and embryonic gonad can differentiate into multiple types of somatic cell.

Stem-cell niche refers to a microenvironment, within the specific anatomic location where stem cells are found, which interacts with stem cells to regulate cell fate. The word 'niche' can be in reference to the in vivo or in vitro stem-cell microenvironment. During embryonic development, various niche factors act on embryonic stem cells to alter gene expression, and induce their proliferation or differentiation for the development of the fetus.

The most entrenched and broadly utilized undifferentiated organism treatment is the transplantation of blood foundational microorganisms to treat illnesses and states of the blood and invulnerable framework, or to restore the blood framework after medicines for particular malignancies. Subsequent to the 1970s, skin undifferentiated organisms have been utilized to develop skin unites for patients with extreme blazes on substantial territories of the body. 

Stem cells are undifferentiated biological cells that can differentiate into specialized cells and can divide (through mitosis) to produce more stem cells. They are found in multicellular organisms. In mammals, there are two broad types of stem cells: embryonic stem cells, which are isolated from the inner cell mass of blastocysts, and adult stem cells, which are found in various tissues. In adult organisms, stem cells and progenitor cells act as a repair system for the body, replenishing adult tissues.

Stem cells technology is a rapidly developing field that combines the efforts of cell biologists, geneticists, and clinicians and offers hope of effective treatment for a variety of malignant and non-malignant diseases. Stem cells are defined as totipotent progenitor cells capable of self-renewal and multiline age differentiation. Stem Cell s technology survives well and show stable division in culture, making them ideal targets for in vitro manipulation. Although early research has focused on hematopoietic stem cells, stem cells have also been recognised in other sites. Research into solid tissue stem cells has not made the same progress as that on hematopoietic stem cells. This is due to the difficulty of reproducing the necessary and precise three dimensional arrangements and tight cell-cell and cell-extracellular matrix interactions that exist in solid organs. 

The sequencing of the human genome, completed at the dawn of the twenty-first century, allows researchers to integrate new data on genetic risk factors with demographic and lifestyle data collected via modern communication technologies. The technical prerequisites now exist for merging these cascades of molecular genetic information, not only to national health registers, but also to epidemiology and clinical data. Long-term storage of biological materials and data is a critical component of any epidemiological or clinical study. In designing Bio banks, informatics plays a vital role for the handling of samples and data in a timely fashion. 

Bio banks play a crucial role in biomedical research. The wide array of bio specimens (including blood, saliva, plasma, and purified DNA) maintained in bio banks can be described as libraries of the human organism. They are carefully characterized to determine the general and unique features of the continuous cell line and the absence or presence of contaminants, therefore establishing a fundamental understanding about the raw material from which the biological product is being derived and maintained. Bio banks catalog specimens using genetic and other traits, such as age, gender, blood type, and ethnicity. Some samples are also categorized according to environmental factors, such as whether the donor had been exposed to radiation, asbestos, or some other substance that can affect human genes. In Bio bank Category the most popular bio bank projects includes cord blood banking, banking stem cells, baby cord blood banking.

Bio marker is a biological molecule found in blood, other body fluids, or tissues that is a sign of a normal or abnormal process, or of a condition or disease. A bio marker may be used to see how well the body responds to a treatment for a disease or condition.

In cancer research and medicine, bio markers are used in three primary ways:

• To help diagnose conditions, as in the case of identifying early stage cancers (Diagnostic)

• To forecast how aggressive a condition is, as in the case of determining a patient's ability to fare in the absence of treatment (Prognostic)

• To predict how well a patient will respond to treatment (Predictive).

Regeneration means the regrowth of a damaged or missing organ part from the remaining tissue. As adults, humans can regenerate some organs, such as the liver. If part of the liver is lost by disease or injury, the liver grows back to its original size, though not its original shape. And our skin is constantly being renewed and repaired. Unfortunately many other human tissues don’t regenerate, and a goal in regenerative medicine is to find ways to kick-start tissue regeneration in the body, or to engineer replacement tissues.

A Biorepository is a biological materials repository that collects, processes, stores, and distributes bio specimens to support future scientific investigation. Biorepositories can contain or manage specimens from animals, including humans, and many other living organisms. Vertebrates, invertebrates, arthropods, and other life-forms are just a few of the many classes of living organisms which can be studied by preserving and storing samples taken. The Biorepository assures the quality, and manages the accessibility and distribution/disposition of the bio specimens in its collection. There are a huge number of bio repositories in the United States, which shift broadly by size, the sort of bio specimen gathered, and reason. One of the bio repository's most elevated needs is ensuring the security and sacredness of individual and medicinal data. Bio specimens are materials taken from the human body, for example, tissue, blood, plasma, and pee that can be utilized for growth determination and investigation. At the point when patients have a biopsy, surgery, or other methodology, regularly a little measure of the example evacuated can be put away and utilized for later research. Once these specimens have been legitimately prepared and put away they are known as human bio specimens. 

Fertility preservation is the effort to help cancer patients retain their fertility, or ability to procreate. Research into how cancer affects reproductive health and preservation options are growing, sparked in part by the increase in the survival rate of cancer patients. The main methods of fertility preservation are ovarian protection by GnRH agonists, cryopreservation of ovarian tissue, eggs or sperm, or of embryos after in vitro fertilization. The patient may also choose to use egg or sperm from a donor by third party reproduction rather than having biological children.

Ethical issues are commonly present in many aspects of Biobanking. The fact that Bio banks deal with human samples, invading an individual autonomy or limiting self-control, provokes a number of ethical issues. Who is actually competent to give informed consent and donate a sample? When individuals donate part of their body to a bio bank, how is that human sample processed? Who is the owner of the sample? Who should decide how it should be used? Who has the right to know individual results of research? These and many more ethical dilemmas exist in the ethical framework of bio banks. With the recent rapid developments in Biobanking, all of these issues are magnified with plenty of further new questions continuously arising. Ethical framework has been the most controversial issue in the domain of bio banking. Thus, it is not surprising that there is a substantial literature focusing on ethical dilemmas in bio banking, such as informed consent, privacy, protection, and returning of results to participants. For many years, researchers at CRB have provided constructive advice on how to deal with ethical aspects of research using human tissue material and personal data. For more than 80 years tissue has been derived from human bodies, stored, distributed and used for therapeutic, educational, forensic and research purposes as part of healthcare routine in most western countries.

Biorepositories provide a resource for researchers to increase understanding of complex diseases. Studies such as the Lung Genomics Research Consortium (LGRC), a two-year project launched in October 2009, are going a step further than standard bio banking practices and characterizing the samples with their molecular makeup. The molecular data can then be mined along with the clinical data. Led by National Jewish Health and funded by the National Heart, Lung and Blood Institute, a division of the National Institutes of Health (NIH), the LGRC project consists of five institutions, including Dana-Farber Cancer Institute. Collaborators in the project work with samples banked at the Lung Tissue Research Consortium (LTRC), which houses tissue samples and blood from lung disease sufferers, primarily chronic obstructive pulmonary disease (COPD), along with a rich set of clinical data from patients.
