Dissecting Engineered Cell Types and Enhancing Cell Fate Conversion via CellNet

Dissecting Engineered Cell Types and Enhancing Cell Fate Conversion via CellNet

Engineering clinically relevant cells in vitro holds promise for regenerative medicine, but most protocols fail to faithfully recapitulate target cell properties. To address this, we developed CellNet, a network biology platform that determines whether engineered cells are equivalent to their target tissues, diagnoses aberrant gene regulatory networks, and prioritizes candidate transcriptional ...

Engineered cell-cell communication via DNA messaging

UNLABELLED BACKGROUND Evolution has selected for organisms that benefit from genetically encoded cell-cell communication. Engineers have begun to repurpose elements of natural communication systems to realize programmed pattern formation and coordinate other population-level behaviors. However, existing engineered systems rely on system-specific small molecules to send molecular messages amo...

CD123bright plasmacytoid predendritic cells: progenitors undergoing cell fate conversion?

CD123(bright) plasmacytoid cells (PC) and CD1c(+) peripheral blood myeloid dendritic cells (DC) are two human DC precursors that can be expanded in vivo by Fms-like tyrosine kinase 3 ligand (FL). It has been proposed that PC and myeloid CD1c(+) DC may represent two distinct lineages of DC. However, the phylogenetic affiliation of PC and its relationship with myeloid DC remain controversial. Her...

Plasmacytoid Predendritic Cells: Progenitors Undergoing Cell Fate Conversion?

Epigenetic regulation in stem cell development, cell fate conversion, and reprogramming.

Stem cells are identified classically by an in vivo transplantation assay plus additional characterization, such as marker analysis, linage-tracing and in vitro/ex vivo differentiation assays. Stem cell lines have been derived, in vitro, from adult tissues, the inner cell mass (ICM), epiblast, and male germ stem cells, providing intriguing insight into stem cell biology, plasticity, heterogenei...
