干细胞注射可以抗衰老吗？ Can stem cells be anti - aging?2016/04/29
A. Have stem cell injections of anti-aging
A: common ectomesenchymal stem cells (MSC), may be at least for the moment I still have a ones.
Mesenchymal stem cells in vivo or in vitro induced specific conditions, can differentiate into a variety of tissue cells, continuous subculture and still have after cryopreservation multi-directional differentiation potential, can be used as ideal seed cells used for tissue damage caused by aging and disease.
So anti-aging is use the pluripotency of mesenchymal stem cells, not against the skin, also has effect for some disease such as cirrhosis of the liver. Do I know this person, oneself use the cured his cirrhosis of the liver.
The common, because this kind of stem cells in the basic no immunogenicity; Lose the quantity and the concentration of cannot too big, generally need to dilute, the side effects of excessive basic similar to blood transfusion. Itself is not a somatic mutation, carcinogenesis and directly from somatic cell difference (concrete relationship with cancer I don’t know).
This is a kind of your own itself some things, effectively strengthen the function of small amplitude.
2. How to guarantee the automatic differentiation of stem cells in the human body needs of the cell?
A: can’t guarantee.
Helpless, biological technology today simply can’t do to control the cell differentiation in the human body.
But, but, but, the complexity of the human body than most people imagine, there are two main are helpful to the technology:
1. The homing potential
Homing refers to refers to the phenomenon of myeloid cells to specific tissues together, like a t-cell precursors converge to the thymus, is the differentiation from bone marrow, where they are needed because the surface receptor specificity to the phenomenon, don’t know understand not to say…
Mesenchymal stem cells have potential of homing, takes initiative to wherever they are needed.
2. Differentiation regulation
Due to the subtle differences between various hormones/signal, consciously make our body’s cells from stem cells into blood cells, liver cells, brain cells, and so on. Between the step on the homing of mesenchymal stem cells, after homing to the need of his place, he will be in the region and the other stem cells induced by the same conditions, who will be divided into the same cell.
Ectomesenchymal stem cells, so usually will automatically run to wherever they are needed, automatically need to differentiate into cells, without human intervention. Like to recruit a group of Allies, command can’t dispatch them, each one handed over to the front commander.
