Here, we have determined whether transcription factor programming of human embryonic stem (hES) cells can be used to generate layer-specific cortical neurons capable of integrating into the stroke-injured rat cortex. Human embryonic stem cells were programmed via overexpression of neurogenin 2 (NGN2). After 7 days, hES-induced neurons (hES-iNs) were characterized in vitro using immunocytochemistry, RT-qPCR, and whole-cell patch-clamp. Cortical ischemic stroke was induced in rats via distal middle cerebral artery occlusion. Forty-eight hours later, hES-iNs were transplanted into the somatosensory cortex adjacent to the ischemic lesion. Three months thereafter, brains were analyzed for expression of neuronal markers, axonal myelination, and synapse formation using immunohistochemistry and immunoelectron microscopy (iEM). Overexpression of NGN2 in hES cells for 7 days generated excitatory neurons, expressing cortical markers at different stages of maturation. After transplantation, the hES-iNs expressed markers of both immature and mature neurons and of upper and deep cortical layers. The hES-iNs sent widespread projections to both hemispheres, and iEM revealed that they were myelinated by host oligodendrocytes and had formed efferent synaptic connections with host cortical neurons. The hES cells programmed via NGN2 overexpression gave rise to subtypes of cortical neurons, capable of integrating structurally into the injured brain, more rapidly than neurons produced by previous protocols. Functional characterization of the grafted hES-iNs and their impact on the balance between brain excitation and inhibition are now highly warranted.

To cope with this demand, HSCs increase their energy production by switching from low ATP-yielding glycolysis to high ATP-yielding mitochondrial oxidative phosphorylation. It is this metabolic switch that enables rapid HSC expansion and differentiation into downstream progeny to increase the immune cell pool and effectively clear the infection. This metabolic switch relies on the sufficient availability of healthy mitochondria as well as fuel in the form of free fatty acids to drive the necessary production of cellular components.

CMs once lost due to injury in the adult heart are never replaced, initiating a viscous cycle of adverse events leading to heart failure. Therapeutic interventions that drive cardiac repair by proliferation of the endogenous CMs or adoptive transfer of stem cells such as cardiac tissue derived stem/progenitor cells (CPCs) are promising albeit limited in their ability to repair the heart. Numerous studies have identified an inherent regenerative power of the heart during embryonic and postnatal development. The developmental cardiac tissue can initiate a robust regenerative response leading to complete resolution of injury. Unique cellular and molecular mechanisms in the developmental heart are at the core of this regenerative ability. Upon cardiac maturation, cellular differentiation and changes in molecular signaling hubs active developmentally are 'switched off' in the adult heart. Recent work has shown convincing results for promoting cardiac repair in the adult heart by reactivation of developmental signaling. CPCs engineering with developmental factors or their CMs specific delivery of can reactivate regenerative signaling to augment cardiac structure and function in the adult heart. This review aims to summarize efforts regarding reactivation of developmental signaling factors in the heart using CPCs and CMs. A special emphasis is on embryonic/developmental microRNAs governed signaling pathways for cardiac repair. We provide an in-depth analysis of the current state of the field including discussion of some of the limitations that will be beneficial for future studies.

These include defined cytokine cocktails, small molecule modulators, stromal co-culture systems, and biomaterials that promote self-renewal while limiting differentiation. We highlight advances in three-dimensional organoid models and microfluidic platforms that better support long-term repopulating cells and reflect native microenvironments. In parallel, progress in gene delivery platforms, including both viral and nonviral approaches, is enabling more efficient and targeted modification of HSCs for therapeutic use in genetic disorders such as sickle cell disease and β-thalassemia.

Our previous meta-analysis indicated the existence of heterogeneous pluripotent states derived from diverse naive protocols. In this study, we characterized a commercial, RSeT-based pluripotent state under various growth conditions. Notably, RSeT hESCs can circumvent the hypoxic growth conditions required by naive hESCs, although some RSeT cells (eg, H1 cells) exhibit much lower single-cell plating efficiency and display altered or significantly retarded cell growth under both normoxia and hypoxia. Importantly, RSeT hPSCs lack many transcriptomic hallmarks of naive and formative pluripotency (the phase between naive and primed states). Integrative transcriptome analysis suggests that our primed and RSeT hESCs are similar to the early stage of post-implantation embryos, in line with previously reported primary hESCs and early hESC cultures. Moreover, RSeT hESCs do not express naive surface markers such as SUSD2 and CD75 at significant levels. At the biochemical level, RSeT hESCs show differential dependence on FGF2 and co-independency on both Janus kinase (JAK) and TGFβ signaling in a cell line-specific manner. Thus, RSeT hESCs represent a previously unrecognized pluripotent state downstream of naive pluripotency.
