Scientists believe that with further research, stem cells are expected to help prevent ageing one day, when as long as hit a agent "youthful vitality secret recipe," human will slow aging. nike jordan shoes,University of Pittsburgh scholars through genetic engineering in the reconstruction of old mice early disease, injection young stem cells, after the mice become more big, strong, life is younger, more healthy mouse three times.
Scientists for 17 days old mice injected stem cells, average life expectancy results 21 days to 28 days of mice have lived more than 66 days, muscle strength and the flow of blood to the brain also increases. cool jordan shoes,Scholars also through laboratory petri dishes the effect of observation stem cells, will the young stem cells and early old cells together, the result let those who were sick, aging cells of the situation was obviously improved.
Stem cells is to origin cells. Stated simply, it is a kind of multiplex differentiation potential and replicate the ability of the original undifferentiated cell, is formed the tissue organ of the mammals primitive cells. Stem cells have the common form, usually a round or oval, the cell, small volume, nuclear is opposite bigger, more than the nucleus for unstained euchromatin, and has high telomerase activity. cool jordan shoes store,Stem cells can be divided into embryonic and adult stem cells. Embrtibuc stem cell development level is higher, it is Totipotent stem cell, and adult stem cells development level is low, is a multipotent or single can stem cells. According to the literatures stem cells are a kind of self-renewal and differentiation potential and keep the undifferentiated state cells. It includes embryonic and adult stem cells. The development of stem cells by many internal mechanism and the influence of the environmental factors. The current human embryonic stem cells can successfully the in vitro culture. The latest study found that adult stem cells can be horizontal differentiation for other types of cells and tissues, and the wide application of stem cells to provide the basis.
