Human iPS cells colonies. The spindle-shaped cells in the background are mouse fibroblast cells. Only those cells comprising the center colony are human iPS cells. Induced pluripotent stem cells (also known as iPS cells or iPSCs) are a type of pluripotent stem cell that can be generated directly from a somatic cell.
Haruko Obokata claimed that STAP cells were produced by exposing CD45 + murine spleen cells to certain stresses including an acidic medium with a pH of 5.7 for half an hour. [6] [7] Following this treatment, the cells were verified to be pluripotent by observing increasing levels of Oct-4 (a transcription factor expressed in embryonic stem cells) over the following week using an Oct4-GFP ...
This stem cell can produce red blood cells, platelets, mast cells, dendritic cells, macrophages, lymphocytes, neutrophils, basophils, and eosinophils. Each of these cells have a different function, but they all work together as part of the immune system. Monocytes can differentiate into either dendritic cells or macrophages.
A stem cell line is a group of stem cells that is cultured in vitro and can be propagated indefinitely. Stem cell lines are derived from either animal or human tissues and come from one of three sources: embryonic stem cells, adult stem cells, or induced pluripotent stem cells. They are commonly used in research and regenerative medicine.
Cell potency is a cell's ability to differentiate into other cell types. [1] [2] The more cell types a cell can differentiate into, the greater its potency.Potency is also described as the gene activation potential within a cell, which like a continuum, begins with totipotency to designate a cell with the most differentiation potential, pluripotency, multipotency, oligopotency, and finally ...
The feat represents the origin of induced pluripotent stem cells, known as iPS cells. [7] In 2011, a female maned wolf, run over by a truck, underwent stem cell treatment at the Zoo Brasília , this being the first recorded case of the use of stem cells to heal injuries in a wild animal. [11] [12]
He serves as Director of Regenerative Biology at the Morgridge Institute for Research in Madison, Wisconsin, is a professor in the Department of Cell and Regenerative Biology at the University of Wisconsin School of Medicine and Public Health and a professor in the Molecular, Cellular, and Developmental Biology Department at the University of California, Santa Barbara.

Much of the research central to embryonic stem cell differentiation and morphogenesis is derived from studies in developmental biology and mammalian embryogenesis. [15] For example, immediately after the blastocyst stage of development (from which ESCs are derived), the embryo undergoes differentiation, whereby cell specification of the inner ...
