7 Reasons To Buy The October Issue Of Men’s Health xSadahiro et al. show that Tbx6 is critical for mesoderm induction and subsequent lineage diversification from pluripotent stem cells (PSCs). Transient Tbx6 expression induced nascent mesoderm and cardiovascular lineages from mouse and human PSCs, whereas prolonged Tbx6 expression suppressed cardiac differentiation and induced somite lineages, including skeletal muscle and chondrocytes.
Following experiments in animals, including those used to create Dolly the sheep, there has been much discussion about the use of somatic cell nuclear transfer (SCNT) to create pluripotent human cells. In SCNT the nucleus of a somatic cell (a fully differentiated cell, excluding germ cells), which contains the majority of the cell’s DNA (deoxyribonucleic acid), is removed and transferred into an unfertilized egg cell that has had its own nuclear DNA removed. The egg cell is grown in culture until it reaches the blastocyst stage. The inner cell mass is then removed from the egg, and the cells are grown in culture to form an embryonic stem cell line (generations of cells originating from the same group of parent cells). These cells can then be stimulated to differentiate into various types of cells needed for transplantation. Since these cells would be genetically identical to the original donor, they could be used to treat the donor with no problems of immune rejection. Scientists generated human embryonic stem cells successfully from SCNT human embryos for the first time in 2013.

Vegetative and Minimally Conscious States Nearly all research to date has made use of mouse embryonic stem cells (mES) or human embryonic stem cells (hES) derived from the early inner cell mass. Both have the essential stem cell characteristics, yet they require very different environments in order to maintain an undifferentiated state. Mouse ES cells are grown on a layer of gelatin as an extracellular matrix (for support) and require the presence of leukemia inhibitory factor (LIF) in serum media. A drug cocktail containing inhibitors to GSK3B and the MAPK/ERK pathway, called 2i, has also been shown to maintain pluripotency in stem cell culture. Human ESCs are grown on a feeder layer of mouse embryonic fibroblasts and require the presence of basic fibroblast growth factor (bFGF or FGF-2). Without optimal culture conditions or genetic manipulation, embryonic stem cells will rapidly differentiate.

Those experiments will surely be followed by many others around the world, as teams in China, the U.K., Singapore, and other nations gain greater control over the remarkable energy of stem cells. With any luck the political and ethical issues may even settle down. Many suspect that with a little more looking, new kinds of stem cells may be found in adults that are as versatile as those in embryos.

The time has come for those cells to prove their reputed mettle.
In 2009 scientists successfully generated retinal cells of the human eye by reprogramming adult skin cells. This advance enabled detailed investigation of the embryonic development of retinal cells and opened avenues for the generation of novel therapies for eye diseases. The production of retinal cells from reprogrammed skin cells may be particularly useful in the treatment of retinitis pigmentosa, which is characterized by the progressive degeneration of the retina, eventually leading to night blindness and other complications of vision. Although retinal cells also have been produced from human embryonic stem cells, induced pluripotency represents a less controversial approach. Scientists have also explored the possibility of combining induced pluripotent stem cell technology with gene therapy, which would be of value particularly for patients with genetic disease who would benefit from autologous transplantation.

All Funding Opportunities Ram Charan There are numerous ways to categorize hair loss. One must first examine the scalp to determine if the hair loss is due to the physical destruction and loss of hair follicles (scarring alopecia). If the scalp appears perfectly normal with plenty of empty hair follicles, this is called non-scarring hair loss. On the other hand, the follicles are permanently destroyed in scarring hair loss. Non-scarring hair loss can also be seen in situations where there is physical or chemical damage to the hair shaft resulting in breakage. Occasionally, it may be necessary to do a biopsy of the scalp to distinguish these conditions. Sometimes, a physician may pull a hair to examine the appearance of the hair shaft as well as the percentage of growing hairs (anagen phase). This article will concentrate on the non-scarring types of hair loss.
