Cardiomyocyte regeneration is limited in adult life and is not sufficient to compensate for cell loss with myocardial infarction. Hence, the identification of a useful source of cardiomyocyte progenitors is of great interest for possible use in regenerative therapy. In this study, we isolated stem cells derived from human subcutaneous adipose tissue. The(More)
Here we report the successful generation and long-term expansion of SOX9-expressing CD271(+)PDGFRα(+)CD73(+) chondrogenic ectomesenchymal cells from the PAX3/SOX10/FOXD3-expressing MIXL1(-)CD271(hi)PDGFRα(lo)CD73(-) neural crest-like progeny of human pluripotent stem cells in a chemically defined medium supplemented with Nodal/Activin/transforming growth(More)
The aim of the present study was to evaluate the potential of acellular dermal matrix as a carrier for delivery of stem cells to the site of soft tissue defect in a murine skin injury model and to determine the potential of stem cells delivered via such an approach to successfully engraft, survive and differentiate locally. We showed that adipose-derived(More)
Soft tissue loss presents an ongoing challenge in reconstructive surgery. Local stem cell application has recently been suggested as a possible novel therapy. In the present study we evaluated the potential of a silk fibroin-chitosan (SFCS) scaffold serving as a delivery vehicle for human adipose-derived stem cells (ASCs) in a murine soft tissue injury(More)
BACKGROUND The aim of this study was to investigate the effect of intracoronary administration of freshly isolated, uncultured autologous tissue-derived stromal cells on cardiac function and perfusion after acute infarction in pigs. METHODS A transmural myocardial infarction in a porcine model was induced by occlusion of the mid LAD with an angioplasty(More)
Here we describe gross and microscopic sweat gland tumors found in a transgenic mouse model of breast cancer, which had transforming growth factor α under the control of mouse mammary tumor virus promoter (MMTV-TGFα). Initially, 20% of the mice in the colony were affected. Cystic lesions formed on the phalanges, palmar surfaces of the metacarpals, and(More)
SUMMARY Here we report the successful generation and long-term expansion of SOX9-expressing CD271 + PDGFRa + CD73 + chondrogenic ectome-senchymal cells from the PAX3/SOX10/FOXD3-expressing MIXL1 À CD271 hi PDGFRa lo CD73 À neural crest-like progeny of human plurip-otent stem cells in a chemically defined medium supplemented with Nodal/Activin/transforming(More)
Tail-tip biopsy for genotyping of genetically modified mice older than 21 d typically is performed by using isoflurane anesthesia. Isoflurane-induced changes in behavior and metabolism can result in unexpected complications and death. We investigated whether cryoanalgesia by using ethylene chloride spray would be an effective local anesthetic for tail-tip(More)
Muscular dystrophies are among major inherited muscle disorders characterized by progressive muscle damage and fibrosis with no definitive cure. Recently, gene or cell based therapies have been developed to restore the missing gene expression or replace the damaged tissues. In order to test the efficiency of these therapies in mice models of muscular(More)
Environmental ultraviolet (UV) exposure exacts a significant toll annually in terms of overall morbidity and undesirable esthetic effects of skin aging. In order to establish the molecular and pathologic basis of this process, the murine model of ultraviolet B (UVB)-induced aging has long been used with reproducibility and success. Although morphometric and(More)
