Can a mother get a fat transfer from a daughter?

No, but anyone can get a fat transplant from their own identical twin. Mother and daughter share half their chromosomes, so tissue transplants would be rejected. Identical twins are genetically identical so they can freely exchange tissues.  Some transplants like kidneys can be close matches, but people still need to take anti-rejection drugs. With an identical twin, the recipient does not see any difference in the new tissue.

   The fat must come from the same individual or an identical twin.  There are many people who can achieve a very nice result with this procedure.Kenneth Hughes, MDLos Angeles, CA

Currently, it is not possible to have someone else's fat transferred. Identical twins are the only ones that can have tissues transplanted from one to the other without immune suppression.

​Hello dear!
Thanks for the question and provided information as well.
No, this is not possible. A BBL is performed using your own fat tissue​.
l recommend you to make an appointment with a board certified plastic surgeon to talk about your goals and anything you need to know.
Good luck :)

Fat transfer can only be done from one body area to another in the same patient. No inter species fat transfer can be done.

No fat can not be transferred from one person to another even if they are related otherwise it would be on the open market

The only transfer from another person will be possible if you had an identical twin. If you gain fat that could help with transferring more volume to the buttocks. 

Unfortunately it is not possible to use any other persons fat for fat transfer. It has to be done with your own fat. Best Wishes,Dr Miami :)
