Bone marrow ‐derived mesenchymal stem cells improve rat islet graft revascularization by upregulating ISL1
This study demonstrated that bone marrow ‐derived mesenchymal stem cells (BMSCs) led to an increase in insulin gene enhancer binding protein‐1 (ISL1) expression in islets and improved the vascular remodeling after islet transplantation in an animal model. Furthermore, the results demonstrate that ISL1 can directly regulate endogenous v ascular endothelial growth factor A (VEGFA) production in islets. These data indicate that ISL1 could be the molecular mediator that led to the effects of BMSCs on islet revascularization. AbstractRevascularization of the islet transplant is a crucial step that defines the success rate o...

Vascularization of human brain organoids
AbstractHuman brain organoids are three ‐dimensional tissues that are generated in vitro from pluripotent stem cells and recapitulate the early development of the human brain. Brain organoids consist mainly of neural lineage cells, such as neural stem/precursor cells, neurons, astrocytes, and oligodendrocytes. However, all human brain o rganoids lack vasculature, which plays indispensable roles not only in brain homeostasis but also in brain development. In addition to the delivery of oxygen and nutrition, accumulating evidence suggests that the vascular system of the brain regulates neural differentiation, migration, an...

Organoid Technology: Current Standing and Future Perspectives
Organoid generation and therapeutic potential AbstractOrganoids are powerful systems to facilitate the study of individuals ’ disorders and personalized treatments. Likewise, emerging this technology has improved the chance of translatability of drugs for pre‐clinical therapies and mimicking the complexity of organs, while it proposes numerous approaches for human disease modeling, tissue engineering, drug developmen t, diagnosis, and regenerative medicine. In this review, we outline the past/present organoid technology and summarize its faithful applications, then, we discuss the challenges and limitations encountered...

Macrophages at the nexus of mesenchymal stromal cell potency ‐ the emerging role of chemokine cooperativity
The MSC and macrophage dyad theorem. MSCs polarize macrophages to an IL ‐10 anti‐inflammatory and regenerative functionality via secretome containing heteroplexed chemokines (and other active factors) or efferocytosis. Both macrophage IL‐10 licensing pathways ‐ MSC function dependent and independent ‐ converge to affect clinical outcomes in inflammatory tissue injury syndromes. AbstractPharmacological depletion of macrophagesin vivo with liposomal clodronate renders mice unresponsive to adoptive transfer of mesenchymal stromal cells (MSCs) for affecting outcomes of acute inflammatory pathology. This experimental ...

Engineered human cardiac microtissues: The state ‐of‐the‐(he)art
The recent advances in cardiac microtissue engineering focused on approaches to recapitulate the adult heart and disease phenotype. The microtissue platform depicted may not be representative of platform used in selected publication and is only a generalization. AbstractDue to the integration of recent advances in stem cell biology, materials science, and engineering, the field of cardiac tissue engineering has been rapidly progressing toward developing more accurate functional 3D cardiac microtissues from human cell sources. These engineered tissues enable screening of cardiotoxic drugs, disease modeling (eg, by using cel...

Label ‐free quality control and identification of human keratinocyte stem cells by deep learning‐based automated cell tracking
A deep learning ‐based automated cell tracking (DeepACT) technology enables the evaluation of keratinocyte culture quality and the identification of keratinocyte stem cells using quantitative cell motion analysis. DeepACT comprises two main modules: identifying human keratinocytes at single‐cell resolution from phase‐contrast images of cultures through deep learning and tracking keratinocyte motion in the colony using a state‐space model. AbstractStem cell ‐based products have clinical and industrial applications. Thus, there is a need to develop quality control methods to standardize stem cell manufacturing. Her...

Sox2 controls neural stem cell self ‐renewal through a Fos‐centered gene regulatory network
Sox2 is necessary for long ‐term neural stem cell (NSC) self‐renewal and for Socs3, Fos, Jun, and Egr2 gene expression. We previously showed that Socs3 overexpression rescues Sox2‐deleted NSC self‐renewal. Fos, Jun, and Egr2 transduction into Sox2‐deleted NSC rescues self‐renewal, Fos alone being both sufficient a nd necessary. Sox2 transduction upregulates Fos and Socs3 in Sox2‐deleted cells, and Fos upregulates Socs3, defining a Sox2‐dependent regulatory network. AbstractThe Sox2 transcription factor is necessary for the long ‐term self‐renewal of neural stem cells (NSCs). Its mechanism of action is s...
