- Failure of cells to work as expected, and.
- The growth of tumors.
Why stem cells are bad?

What is the tissue from a miscarriage?
The tissue (the fetus, gestational sac, and placenta) from an early miscarriage may not be obvious to the naked eye. Many early miscarriages look like heavy menstrual periods. In a miscarriage that happens beyond 6 weeks, more tissue will be expelled. The expelled tissue usually resemble large blood clots.
