The Polar body refers to the resultant structure that an egg cell (oogonium) produces as it undergoes meiosis. During the first stage of meiosis, the egg cell evenly divides the chromosomes between the resultant two cells. However, the cytoplasm is divided unevenly. One of the cells retains majority of the cytoplasm, leaving the other cell with a very small amount …
Somatic stem cells are basically adult stem cells that are found in both children and adult humans. The Regeneration center uses adult stem cells that are isolated from a tissue samples from cord blood,placenta,adipose (fat) or dental pulp. Embryonic vs Somatic Stem Cells (Adult) Somatic stem cells, also known as adult stem cells, are a type of undifferentiated cell found …
Tetraploid complementation assays are used to examine the potency of a particular stem cell. Scientific studies in medical journals performed on chimeras (the mixture of cells of two distinct animals) revealed that the fusion of two embryos with eight cells resulted into cells containing four sets of chromosomes referred to as tetraploid cells, which are predisposed to developing into an …
Zygotes are single cell that is generated after the egg has been fertilized by the sperm. The zygote then merges chromosomes from both of the gametes. After which, several divisions will take place for the production of embryonic cells at roughly four days after fertilization. The zygote stage lasts for only about 4 days in total. On and around the 5th …
Culture medium also called growth medium pertains to the liquid medium necessary to carry out a culture and sensitivity test. The substance acts as a mode of support and nourishment for the cells undergoing culture, and may also contain growth factors necessary to generate cell change. Cell culture medium, often referred to as growth medium, is a nutrient-rich solution used …
Adipose tissue pertains to fat, which is primarily made up of fat cells known as adipocytes. [1] Adipose stem cells or “ASCs” are an source of therapeutic mesenchymal cells for younger patients or those seeking cosmetic treatments like stem cell breast treatment and stem cell facelifts. Unlike the limited quantities of bone marrow derived stem stem cells “BMSCs” The adipose …
