A Tissue-Engineered Microvascular System to Evaluate Vascular Progenitor Cells for Angiogenic Therapies
(2015)The ability of tissue engineered constructs to replace diseased or damaged organs is limited without the incorporation of a functional vascular system. To design microvasculature that recapitulates the vascular niche functions ... -
Age-related changes in the cellular composition and epithelial organization of the mouse trachea.
(PloS one, 2014-01)We report here senescent changes in the structure and organization of the mucociliary pseudostratified epithelium of the mouse trachea and main stem bronchi. We confirm previous reports of the gradual appearance of age-related, ... -
Airway basal stem cells: a perspective on their roles in epithelial homeostasis and remodeling.
(Dis Model Mech, 2010-09)The small airways of the human lung undergo pathological changes in pulmonary disorders, such as chronic obstructive pulmonary disease (COPD), asthma, bronchiolitis obliterans and cystic fibrosis. These clinical problems ... -
Arterial pole progenitors interpret opposing FGF/BMP signals to proliferate or differentiate.
(Development, 2010-09)During heart development, a subpopulation of cells in the heart field maintains cardiac potential over several days of development and forms the myocardium and smooth muscle of the arterial pole. Using clonal and explant ... -
Hedgehog signaling antagonist promotes regression of both liver fibrosis and hepatocellular carcinoma in a murine model of primary liver cancer.
(PLoS One, 2011)OBJECTIVE: Chronic fibrosing liver injury is a major risk factor for hepatocarcinogenesis in humans. Mice with targeted deletion of Mdr2 (the murine ortholog of MDR3) develop chronic fibrosing liver injury. Hepatocellular ... -
Identification of select glucocorticoids as Smoothened agonists: potential utility for regenerative medicine.
(Proc Natl Acad Sci U S A, 2010-05-18)Regenerative medicine holds the promise of replacing damaged tissues largely by stem cell activation. Hedgehog signaling through the plasma membrane receptor Smoothened (Smo) is an important process for regulating stem cell ... -
Interstitial engraftment of adipose-derived stem cells into an acellular dermal matrix results in improved inward angiogenesis and tissue incorporation.
(J Biomed Mater Res A, 2013-10)Acellular dermal matrices (ADM) are commonly used in reconstructive procedures and rely on host cell invasion to become incorporated into host tissues. We investigated different approaches to adipose-derived stem cells (ASCs) ... -
Ligament-derived matrix stimulates a ligamentous phenotype in human adipose-derived stem cells.
(Tissue Eng Part A, 2010-07)Human adipose stem cells (hASCs) can differentiate into a variety of phenotypes. Native extracellular matrix (e.g., demineralized bone matrix or small intestinal submucosa) can influence the growth and differentiation of ... -
Patient-derived endothelial progenitor cells improve vascular graft patency in a rodent model.
(Acta Biomater, 2012-01)Late outgrowth endothelial progenitor cells (EPCs) derived from the peripheral blood of patients with significant coronary artery disease were sodded into the lumens of small diameter expanded polytetrafluoroethylene (ePTFE) ... -
Ras controls melanocyte expansion during zebrafish fin stripe regeneration.
(Dis Model Mech, 2010-07)Regenerative medicine for complex tissues like limbs will require the provision or activation of precursors for different cell types, in the correct number, and with the appropriate instructions. These strategies can be ... -
Regulation of Progenitor Cell Proliferation During Zebrafish Fin Regeneration
(2009)Vertebrates like urodele and teleost have an enhanced capacity for regeneration, when compared to mammals. Recently, the teleost zebrafish (Danio rerio) has become a popular model for studying regenerative events, due to ... -
The exon junction complex component Magoh controls brain size by regulating neural stem cell division.
(Nat Neurosci, 2010-05)Brain structure and size require precise division of neural stem cells (NSCs), which self-renew and generate intermediate neural progenitors (INPs) and neurons. The factors that regulate NSCs remain poorly understood, and ... -
Tissue engraftment of hypoxic-preconditioned adipose-derived stem cells improves flap viability.
(Wound Repair Regen, 2012-11)Adipose-derived stem cells (ASCs) have the ability to release multiple growth factors in response to hypoxia. In this study, we investigated the potential of ASCs to prevent tissue ischemia. We found conditioned media from ...
