The yield of CD34<sup>+</sup> cells was substantially higher in the UC-MSC co-culture group. The hiPSCs exhibited comparable reprogramming efficiency, pluripotency marker expression, trilineage differentiation potential, and genomic stability to CD34<sup>+</sup> cells expanded under standard culture conditions.

Previous studies, guided by developmental hematopoiesis, made progress in creating blood cells from hiPSCs, but challenges persisted in producing hematopoietic cells with functional properties of genuine HSCs capable of long-term engraftment. In their recent study, Ng and colleagues described an optimized differentiation protocol that manipulates key signaling pathways, including TGF-β, WNT, BMP, and retinoic acid in a stage-specific manner to generate HSCs with multilineage capacity. This strategy yielded hematopoietic cells capable of engrafting long term with high levels of human chimerism in recipient mice.

Indeed, senescent cells and their secretome play a crucial role during limb development. However, whether the process of limb regeneration also relies on senescent cells remains unclear. Creation of a novel targeted depletion strategy that can eliminate senescent cells in the regenerating limb has now demonstrated an important role for senescent cells in limb regeneration.
