Adult dry cell is proliferous outside body too long likelihood happening canceration

Study the report hints: If adult dry cell is proliferous outside body too long, produce canceration likely.

Outside dividing remedial blood disease at present, study before what dry cell transplants to already entered the major disease such as exhaustion of coronary heart disease, diabetic, liver function is clinical, journal of medicine of newest first phase " cancer studies " reported the new discovery of the scientist of Spain and Denmark: Dry cell transplanting has potential risk.
Study the report hints: If adult dry cell is proliferous outside body too long, produce canceration likely.
Professor of heart of accept of Er of rich of university of Spanish Madrid autonomy says, grown dry cell (commonly used do a cell at treating the marrow of leukaemia) transplanting is considered as safety all the time. But his research discovery, if grow up,dry cell breaks up outside body the frequency is too much, not safe.
He 8 months are bred outside body in, broke up the 90 human body to 140 generation fill transplanting of qualitative dry cell to come inside animal body hind, the " cell that discovers " is the oldest produced canceration. Observation shows: Outside groovy body enlarge adds the 6 human body to 8 weeks to fill those who pledge dry cell is safety, but breed outside body exceed 4 to arrive 5 months, this kind of dry cell can happen initiative change. This one discovery supports tumor to do a cell to may come from the hypothesis of grown dry cell. Study clew, the clinical treatment latent capacity that does a cell for sufficient development, indispensible fill qualitative dry cell to undertake biology security studies to human body.
Buruiensi's research also discovers hospital of university of Danish Ou Dengsai, the dry cell that fosters for long outside body may produce canceration. Its reason is its begin to create end bead is enzymatic. Carry an action that bead of enzymatic end stop having block follows segmentation and shortens gradually, stabilize the extreme of chromosome thereby, main effect has in maintaining sex of " of cellular " eternal life. He says, permanent open the upright bead enzymatic gene that fills qualitative dry cell, will make its become cancer cell finally.
Two experts think, at present of short duration but 60 generation left and right sides regards will dry segmentation as cut off, but affirmatory safety limit is restricted to still need to do more research. At the same time " need differentiates clearly dry cell enlarge adds safe boundary, even if bead of for no reason is enzymatic generated cell also needs " ; And the potential risk that two research prove to do a cell. Accordingly they emphasize, should do comprehensive and safe test before any phyletic dry cells are used at cure.
