A embryonic stem cells

It takes 7 days for a new red blood cell to develop from stem cells. Stem cells are similar to base cells. They can also be seen as a general template from which specialized cells are made. Stem cells can be taken from a newborn baby's umbilical chord or extracted from an adult blood donor's blood.
For example.
A red blood cell lives for between 100 and 120 days. Then these are aided by stem cells as they become red blood cells.
