For years through an extensive array of investigative researches throughout the international continuum it has come to the knowledge that stem cells are able to fight with the gradual aging process through the refilling of old or damaged cells especially in the skin, gut, and blood through its incessant supply for the maintenance and repair of the tissue. However, according to a new investigative report that has come to the fore in the recent days it has been found that the aforementioned capacity of the stem cells suffers a steady degeneration with the progress of age for their acquiring of functional defects.   

It is to be noted in this esteem that the initiative was taken by Stuart Chambers, Margaret Goodell, and their colleagues at the Baylor College of Medicine for the investigation of the molecular mechanisms of the aging of stem cells while rendering a close attention at the gene expression profiles of aging hematopoietic stem cells (HSCs), known as the originators of blood cells. According to the study of these eminent researchers, the genes involved in the inflammatory and stress response were identified as becoming more active with the growth of age while at the same time genes imperative for the directive of the gene expression and genomic integrity became less active. In short, these results indicate strongly to the notion that in due process the HSCs acknowledge the wearing away of aging, that also are amply visible in respect of the other cells while at the same time tend to contrite on the mechanisms of aging.

As a part of the process for the studying of the regenerative competence of the HSCs' in due course, the responsible Chambers and colleagues were left with no other choice than to isolate the HSCs from young (aged 2 months) and old (aged 21 months) mice. It was then followed through the process of transplantation of either young or old cells into mice, the bone marrow cells of whose were badly affected by the process of radiation. As a result of the investigation it became apparent that the were capable to give rise to the innovative marrow cells in the same pace within the next four weeks subsequent to the transplantation. However, at the eighth and 16 weeks following the transplantation the role of the old HSCs' were visible to be in a reduced mode considerably symptomatic of the notion that the repopulating capacity of the HSCs were on the wane. It its turn it is implied that the findings indicated that the genes that were involved in the provocative response were expressed more with the gradual elevation of the ages of the HSCs with effective evidence of connecting inflammation and aging in the kidney, brain, and arteries.
