Organogenesis relies on the spatiotemporal balancing of differentiation and proliferation driven by an expanding pool of progenitor cells. In the mouse pancreas, lineage tracing at the population level has shown that the expanding pancreas progenitors can ...
ATP is a key molecule of cell physiology, but despite its importance, there are currently no methods for monitoring single-cell ATP fluctuations in live bacteria. This is a major obstacle in studies of bacterial energy metabolism, because there is a growin ...
Several treatments have been developed for treating bone fractures as they are very common events. Amongst other new strategies, synthetic bone substitutes present a very high potential therapy because they lower the risk of infection and rejection. Moreov ...
Divergent morphology of species has largely been ascribed to genetic differences in the tissue-specific expression of proteins, which could be achieved by divergence in cis-regulatory elements or by altering the binding specificity of transcription factors ...
Stem cells play a key role in a wide range of biological processes, in large part due to their ability to self-renew or differentiate into specialized cell types in response to various biological cues. In vivo, stem cells reside in a complex microenvironme ...
A microfluidic in vitro cell encapsulation platform to systematically test the effects of microenvironmental parameters on cell fate in 3D is developed. Multiple cell types including fibroblasts, embryonic stem cells, and cancer cells are incorporated in e ...
Tissue engineering scaffolds are the new approach to replace common bone grafts. The first aim of this project was to investigate whether bone progenitor cells used in previous studies can undergo osteogenic differentiation. In osteogenic staining experime ...
Stem cell therapies hold tremendous potential for tissue and organ regeneration. Yet, there remains significant need for better ex vivo culture and manipulation methods. On the one hand, many tissue-specific stem cells cannot be propagated without causing ...
Multiple molecular and physical cues engage in complex interplay to afford the fine control over stem cell behavior that is required during tissue development, homeostasis, and repair. As a result of a close collaboration between biologists, engineers, and ...
Reactivation of human cytomegalovirus (HCMV) is a significant cause of disease and death in immunocompromised patients underscoring the need to understand how latency is controlled. Here we demonstrate that HCMV has evolved to utilize cellular miRNAs in ce ...
