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 …
Obligatory asymmetric replication is also known as asymmetric cell division is the process by which a stem cell undergoes differentiation or division. The final result of which are two daughter cells. [1] One cell is identical to the mother cell and the other a totally differentiated one. This is one of the processes in regenerative medicine that allows stem cells …
The word “In vitro” Latin translation, is simply “in glass.” In modern times this means an in-vitro environment is simply in a test tube or laboratory dish that holds the cell culture medium or substance necessary to perform a culture test or fertilization.[1] In vitro fertilization (IVF) is a medical procedure in which eggs and sperm are combined outside the …
Macrophage are specific type of WBC or white blood cells, which are known to have a versatile functionality inside and for the immune system. Dendritic Cells and Macrophages (VIDEO) Macrophages are known as the body’s first line of defense against invasion from viruses and bacteria, Macrophages are generally responsible for safeguarding our inter-cellular environment by killing several types of bacterias. …
Human embryonic stem cell line or hESC are also referred to as simply Embryonic stem cells. ES cells pertains to a pluripotent lineage of cells that are typically derived from a human embryo (after zygote) at its earliest stage. Embyronic Stem Cell Biology Embryonic cells of the morular are totipotent. ES cells are considered very powerful in regenerative medicine since they …
The Germ layers consist of about three layers of cells: Ectoderm – exterior germ layer Mesoderm – middle germ layer Endoderm – internal germ layer These three distinct layers are formed after a blastocyst’s inner cell mass undergoes a process of specific organization called gastrulation,[1] which occurs after the blastocyst phase in embryonic development. Organization or Gastrulation [2] involves many things including distinct differentiation patterns …
