Harnessing the potential of human stem cells for modeling the physiology and diseases of cortical circuitry requires monitoring cellular dynamics in vivo. We show that human induced pluripotent stem cell (iPSC)-derived cortical neurons transplanted into th ...
Midbrain dopaminergic (mDA) neurons degenerate in Parkinson’s disease and are one of the main targets for cell replacement therapies. However, a comprehensive view of the signals and cell types contributing to mDA neurogenesis is not yet available. By anal ...
Hematopoietic stem cells (HSCs) are responsible for the continuous production of all blood cells. This unique ability has made it possible to successfully use HSCs in the clinical setting to remedy various blood disorders. However, despite six decades of r ...
Down syndrome (DS) or trisomy 21 is the most frequent genetic cause of intellectual disability in children and adults. Although numerous studies have shown that cognitive impairment possibly arises from dysfunction of the hippocampal circuit, there has bee ...
Whether new neurons are added in the postnatal cerebral cortex is still debated. Here, we report that the meninges of perinatal mice contain a population of neurogenic progenitors formed during embryonic development that migrate to the caudal cortex and di ...
The complex cellular microenvironment plays an important role in determining cell fate. For example, stem cells located in a microenvironment termed niche integrate a wide variety of extrinsic cues to take distinct fate choices. Capturing this multiple-inp ...
The speed of stem cell differentiation has to be properly coupled with self-renewal, both under basal conditions for tissue maintenance and during regeneration for tissue repair. Using the Drosophila midgut model, we analyze at the cellular and molecular l ...
Cell replacement therapies for neurodegenerative disease have focused on transplantation of the cell types affected by the pathological process. Here we describe an alternative strategy for Parkinson's disease in which dopamine neurons are generated by dir ...
Although stem cells hold tremendous potential for clinical applications, their in vitro manipulation remains very challenging. In vivo, stem cells reside in intricate 3D microenvironments, termed niche, in which many local and systemic extrinsic factors ar ...
Rod-shaped bacteria typically grow first via sporadic and dispersed elongation along their lateral walls and then via a combination of zonal elongation and constriction at the division site to form the poles of daughter cells. Although constriction compris ...
