Mesenchymal stem cell (MSC)-based therapies have generated much hope and promise as a potential source of cells for cell-based therapeutic strategies in pediatric degenerative diseases. However, the distribution and migratory routes of MSCs are unknown. Here, real-time PCR and microscopy were used to observe the migration and distribution of labeled human MSCs (hMSCs) transplanted into the striatum...
We previously identified the tumor suppressor INT6/eIF3e as a novel down regulator of HIF2α. Small interfering RNA targeting Int6 (siRNA-Int6) in HeLa cells led to normoxic stabilization of HIF2α, with concomitant transcription of angiogenic factors, including angiopoietin, basic fibroblast growth factor, and vascular endothelial growth factor. Here we used HIF2α normoxic up-regulation via Int6 silencing...
Chemokines play an important role in the migration of a variety of cells during development. Recent investigations have begun to elucidate the importance of chemokine signaling within the developing nervous system. To better appreciate the neural function of chemokines in vivo, the role of signaling by SDF-1 through its CXCR4 receptor was analyzed in zebrafish. The SDF-1-CXCR4 expression pattern suggested...
