Background. Vascularized composite allografts (VCA) have demonstrated good clinical outcomes dependent on chronic immunosuppression. Previous work by our group and others supports that cotransplanted vascularized bone marrow (VBM) as a component of VCA offers immunologic protection to prolong graft survival. We aimed to characterize the requirement...
Organ scaffold bioengineering is currently limited by the inability to effectively repopulate the scaffold with appropriately distributed functional cells. We examined the feasibility of a decellularized liver scaffold to support the growth and function of multilineage allogenic cells derived from either adult or neonatal liver cells. Cell slurries...
Recent years have seen a proliferation of methods leading to successful organ decellularization. In this experiment we examine the feasibility of a decellularized liver construct to support growth of functional multilineage cells. Bio-chamber systems were used to perfuse adult rat livers with 0.1% SDS for 24 hours yielding decellularized liver scaf...
The greatest interpretive challenge of modern medicine may be to functionally annotate the vast variation of human genomes. Demonstrating a proposed approach, we created a library of BRCA2 exon 27 shotgun-mutant plasmids including solitary and multiplex mutations to generate human knockin clones using homologous recombination. This 55-mutation, 13-...
P311 is an 8 kDa protein highly expressed in brain and vascular smooth muscle (VSM). Telemetry and VPR tail cuff plethysmography demonstrated that p311 ‐null (P311 KO) mice exhibit pronounced systemic hypotension in the absence of phenotypic abnormalities. Myography and collagen gel contraction studies revealed a severe decrease in blood vessel and...
We previously identified a set of transcription regulators, referred to as TIPs (tension-induced/inhibited proteins), with a role in myogenic versus adipogenic differentiation. Here we report that the TIP family comprises eight isoforms,
all bearing a SANT (switching-defective protein 3, adaptor 2, nuclear receptor corepressor, and transcription fa...
P311 is an 8-kDa protein originally found in neurons and muscle. We recently showed that expression of P311 in NIH 3T3 cells induced a myofibroblast phenotype with low TGF-beta1 expression. Here we demonstrate that P311 downregulates not only TGF-beta1, but also TGF-beta2, expression, with no effect on TGF-beta3. In addition, P311 interacts with TG...
