All cells have to eventually duplicate. in nature, there are 2 main methods of cell duplication. Mitosis and Meiosis. The Process of Mitosis Mitosis is the exact opposite of cell duplication through meiosis where the chromosome population is split in half. [1] This fundamental process of cell division allows for each new cell to retain their original chromosome numbers, allowing …
A Stem cell niche pertains to the particular tissue area where stem cells exist. The actual word ‘niche’ means the medium was “live” in vivo or in a lab or in-vitro microenvironment. [1] Recent journals and clinical studies on Mesenchymal cells from diverse systems have shown that stem cell function is controlled by extracellular cues from the niche and by …
Long-term self-renewal in regen medicine refers to the capability stem cells have for self-replication through continuous division. The result of this natural regeneration cycle is common amongst certain types of non-specialized cells. The process of self-renewing usually occurs over a long period (that could even run for years), and the length and rate of self-renewal is determined on the specific …
Somatic cell nuclear transfer (SCNT) is a procedure in which the nucleus of an adult or somatic cell is inserted into an enucleated egg for the creation of an embryo. In-Vivo a nucleus, which contains a persons DNA, somatic cell is removed from its vessel and the rest of the cell cultures are discarded. Somatic cells are found in adult stem …
Oligopotent cell lines have the ability to transform into quite a limited number of several other types of cells, an example of which is a myeloid cells,B cells, T cells, plasma cells, NK Cells or the cells comprising the lymphoid system. An example of Oligopotent Cells are myeloid cell can differentiate into any of the blood stem cells found in …
Telomeres are essentially the “butts” of single cell chromosomes. They are the tail end of a repetitive DNA structure that is highly related to your typical sequence of DNA that has undergone replication over and over again in a very distinct manner. A telomere will first neutralize a chromosomes’ predisposition/pre-programmed instructions to shorten with copy it makes. In other words, Telomeres …
