The authors discuss the various stem cell types identified in rodent and human hair follicles and ongoing studies on the potential use of hair follicle stem cells for skin, bone, cardio-vascular, and nerve tissue engineering.
Investigators showed that gene-edited, immune-evasive cell grafts could survive and successfully treat diseases in immunocompetent, fully allogeneic recipients. A mixture of endothelial cells and cardiomyocytes was injected into infarcted mouse hearts, and both cell types orthotopically engrafted in the ischemic areas.

Modeling colorectal cancer (CRC) using organoids has burgeoned in the last decade, providing enhanced in vitro models to study the development and possible treatment options for this type of cancer. The authors describe both normal and CRC intestinal organoid models and their utility in the cancer research field.

Researchers reported the single-cell characterization of the differentiation of pancreatic duct-like organoids from human induced pluripotent stem cells (hiPSCs) on a microwell chip that facilitated the uniform aggregation and chemical induction of hiPSC-derived pancreatic progenitors.
Researchers combined human iPSCs and airway-on-a-chip technology to demonstrate the effectiveness of fluid shear stress for regulating the global axis of multicellular planar cell polarity, as well as inducing ciliogenesis, thereby contributing to quantifiable unidirectional mucociliary flow.
Scientists proposed a novel strategy to generate hindbrain serotonin (5-HT) neurons from human PSCs, which involved the formation of ventral-type neural progenitor cells and stimulation of the hindbrain 5-HT neural development.
JMJD3 has been found to enhance self-renewal ability and reduce the differentiation capacity of ESCs and multipotent stem cells. The authors discuss the recent advances of JMJD3 function in stem cell fate.
Researchers from the University of Sydney have been awarded $6.3 million for three projects which will address stem cell derived-retinal organoids for blindness in adults, iPSC derived cardiomyocytes for chronic heart failure, and help to improve decisions about access to stem cell interventions.
