Emerging evidence suggests that apoptosis regulators and executioners may control cell fate, without involving cell death per se. Indeed, several conserved elements of apoptosis are integral components of terminal differentiation, which must be restrictively activated to assure differentiation efficiency, and carefully regulated to avoid cell loss. A better understanding of the molecular mechanisms underlying key checkpoints responsible for neural differentiation, as an alternative to cell death will surely make stem cells more suitable for neuro-replacement therapies. In this review, we summarize recent studies on the mechanisms underlying the non-apoptotic function of p53, caspases, and Bcl-2 family members during neural differentiation. In addition, we discuss how apoptosis-regulatory proteins control the decision between differentiation, self-renewal, and cell death in neural stem cells, and how activity is restrained to prevent cell loss.
