Aishwarya Rai Bachchan promotes stem cell banking (view pics)

Aishwarya revealed that even she and husband Abhishek opted for stem cell banking when their daughter Aaradhya was born.

"I had always banked that thought even before I got married. At that point of time we were contacted by a lot of companies and closer to the date we interacted extensively with Life Cell. Once were convinced we went ahead with the decision to bank with Life Cell," Aishwarya said.

Aishwarya urges expecting parents to look at it as a sensible investment.

"To those who can afford it, we really look at a lot of expenses. A lot of indulgences are so easily spent upon that somehow this thereby seems like a sensible investment," Aishwarya said.
