Totipotent cells are the complete *saksham* ones, like a fertilized egg, and unipotent cells can only make their own type. Yamanaka's factors are like a time machine, turning old cells young again. But as a parent, I see the *vyapar* in this science—these banks sell peace of mind by freezing what is, frankly, already obsolete compared to what labs can now reprogram. My own father’s *khaas* advice was to invest that lakh in her education instead, because by the time she might need it, they’ll likely grow what’s needed from a skin cell.
