One of the major challenges in cell implantation therapies is to promote integration of the microcirculation between the implanted cells and the host. We used adipose-derived stromal vascular fraction (SVF) cells to vascularize a human liver cell (HepG2) implant. We hypothesized that the SVF cells would form a functional microcirculation via vascular assembly and inosculation with the host vasc...

Stem cells therapy has been suggested as a promising option for the treatment of acute kidney injury (AKI). This study was performed to compare the abilities of xenogenic transplantation of human adipose stromal vascular fraction (SVF) and adipose-derived mesenchymal stem cells (AdMSCs) to facilitate the recovery of renal function and structure in a rat model of ischemia/reperfusion (IR) induce...

Partial replacement of chondrocytes by stem cells has been proposed to improve the performance of autologous chondrocyte implantation (ACI). Our previous studies showed that the increased cartilage production in pellet cocultures of chondrocytes and mesenchymal stem cells (MSCs) is due to a trophic role of the MSCs by stimulating chondrocyte proliferation and matrix production rather than MSCs ...

Street vended food (SVF) includes food and beverages prepared and sold outdoors or in public areas by street merchants for consumption on the scene or later without further preparation. Due to its low price and convenience, SVF has been popular in Korea for a long time, particularly with high school students. Beyond Korea, SVF is also popular in southeast Asia and southern Africa in the form of...

BACKGROUND The pericytes in the blood vessel wall have recently been identified to be important in regulating vascular formation, stabilization, remodeling, and function. We isolated and identified pericyte-like platelet-derived growth factor receptor beta-positive (PDGFRβ+) cells from the stromal vascular fraction (SVF) of adipose tissue from critical limb ischemia (CLI) patients and investiga...

Stem cells isolated from adipose tissue show great therapeutic potential in veterinary medicine, but some points such as the use of fresh or cultured cells and route of administration need better knowledge. This study aimed to evaluate the effect of autologous stromal vascular fraction (SVF, n = 4) or allogeneic cultured adipose-derived stem cells (ASCs, n = 5) injected into acupuncture points ...

MATERIALS AND METHODS: The potential healing benefits of HBOT preconditioning and stromal vascular fraction (SVF) delivery on flap survival were examined in a guinea pig model. Animal subjects were randomly assigned to one of four study groups: SVF/saline injections followed by HBOT, SVF/saline injections only, HBOT only, or neither HBOT nor injections. In order to enhance clinical relevance, a...

tures from geographic information databases. The model outputs are: sun location in Cartesian coordinates; grid cells in shadow and sun; sky view factor in every grid cell; direct and diffuse partition; and finally, the total short wave radiation by each grid cell. Sky view factor and reflections are calculated using a three-dimensional ray tracking method. It consists in casting rays from an h...
