Project description:Mechanism controlling cell fate remains elusive. Chromatin remodeling complex interacts with transcription factors to colocalize across the genome and regulate region-specific epigenetic environment. Here, we propose an engineering approach for controlling cell fate through chromatin closing and opening. We utilize chromatin remodeling complex, BAF, known to activate gene expression by opening chromatin loci. By grafting BAF interacting motifs onto Nanog, we show that engineering factors could promote somatic cell reprogramming with Oct4. Furthermore, mutation on the interacting motifs render iPSC generation. The syntactic factors facilitate cell fate transition by recruiting BAF complex to modulate chromatin accessibility and reorganize cell state specific enhancers. Our findings reveal alternative methods to control cell fate by manipulating chromatin accessibility.

Project description:We report that macrophage elasticity plays a dominant role in bacterial phagocytosis, release of TNF-alpha, and production of reactive oxygen species. We show that macrophage elasticity is modulated by mechanical factors including substrate rigidity and substrate stretch. Changes in macrophage elasticity are dependent upon the degree of actin polymerization, and mediated in part through small rhoGTPase activity. Moreover, the functional effects of macrophage elasticity are not predicted by gene expression profiles.

Murine RAW 267.4 macrophages were separately grown on 2 matrix stiffness levels (1200, 150000 Pascals) for 0, 2, 6, 18 hours with 3 replicate sample experiments per condition. Total RNA extracted from the cells and profiled by microarrays. Keywords: Murine RAW 267.4 macrophage, matrix stiffness, phagocytosis, cell elasticity.
