Question is : legitimate stem cell clinics ?

Good question.

Legal basis of tratamento com células-tronco in different countries is different.

The main thing is to use stem cells ethically, so that patient will get positive response, not harm.

Unethical use – fetal stem cells from the fetus.
Ethical and morally – autologous stem cells or cultivated.
