Trans-differentiation takes place without reprogramming of developmental-specific DNA methylation, a key determinant of stable cell identity [RRBS]

Project description:A number of studies have demonstrated that it is possible to directly convert one cell type to another by factor-mediated trans-differentiation, but in the vast majority of cases, the resulting reprogrammed cells are unstable in the sense that they are unable to maintain their new cell identity. To better understand this phenomenon, we have developed a new analytical approach for better characterizing trans-differentiation-associated changes in DNA methylation, a major determinant of long-term cell identity. By examining various models of trans-differentiation both in vitro and in vivo, our studies indicate that despite convincing expression changes, trans-differentiated cells seem unable to alter their original developmentally-mandated methylation patterns. We propose that this blockage is due to basic developmental limitations built into the regulatory-sequence that govern epigenetic programming of cell identity. These results shed new light on the molecular rules of stable somatic cell reprogramming.

Trans-Seq for mammalian retinotectal circuit mapping

Project description:The mouse visual system serves as an accessible model to understand mammalian circuit wiring. Despite rich knowledge in retinal circuits, the long-range connectivity map from distinct retinal ganglion cell (RGC) types to diverse brain neuron types remains unknown. Here we developed an integrated approach, named Trans-Seq, to map RGC to superior collicular (SC) circuits. Trans-Seq combines a fluorescent anterograde transsynaptic tracer, consisting of codon-optimized wheat germ agglutinin fused to mCherry, with single-cell RNA Sequencing. We used Trans-Seq to classify SC neuron types innervated by genetically-defined RGC types and predicted a neuronal pair from αRGCs to Nephronectin-positive wide-field neurons (NPWFs). We validated this connection using genetic labeling, electrophysiology, and retrograde tracing. We then utilized transcriptomic data from Trans-Seq to identify Nephronectin as a determinant for selective synaptic choice from αRGC to NPWFs via binding to Integrin-α8β1. The Trans-Seq approach can be broadly applied for postsynaptic circuit discovery from genetically-defined presynaptic neurons.

Gene expression profiles of CD4SP Foxp3GFP-CD25+ Treg precursors and Foxp3GFP-CD25- thymocytes

Project description:We investigated at which stage of maturation commitment to a stable Foxp3-expressing phenotype takes place. We assessed stability of Foxp3 expression in thymic Foxp3+ Treg subsets of different maturity, defined by CD24 expression. Next we compared gene expression profiles of Foxp3+ Treg subsets (+) of different maturity (24lo, 24int, 24hi) and could identify a set of genes that were specifically up or downregulated in Foxp3+ Tregs, but not in Foxp3- conventional T cells, in a maturation-dependent manner.
