Stem cell type Description Examples
Totipotent Each cell can develop into a new individual
Cells from early (1-3 days) embryos
Pluripotent Cells can form any (212) cell types
Some cells of blastocyst (5 to 14 days)
Multipotent Cells differentiated, but can form a number of other tissues
Fetal tissue, cord blood, and adult stem cells
Unipotent Cells differentiated, into one cell lines Neural Stem cells, etc..

Option Advantages Disadvantages
The Garbage can •No cost•No headaches
•Wasting of valuable stem cells
Public cord blood banking(donation)
•Can be used by anyone in need•Increases the pool of HSC donors•Increases the pool of minority donors•No cost to the donor
•Needs public/government financial support•Not designated for the donor / family
Private cord blood collection
•Saved for own use•Future potential ??? Regenerative use ??
•Cost $$$•Will probably never be used•Socioeconomic disparity•Reducing public pool•Professional liability•Legal/ownership issues•Safety of use•Viability, duration of storage
