background differences in causes, severities, areas of stenosis, and the association with swallowing and phonation of larynx and trachea can result into laryngotracheal stenosis (lts).this study evaluated the healing effect of bone marrow stem cells (bmscs) in experimentally induced lts dog model. methods seven dogs were enrolled. bmscs were isolated from proximal humerus and shoulder of a dog ...

The human amniotic membrane known as the innermost single epithelial-covered layer provides many applications such as applicable anti-inflammatory and anti-cancer effects. These immunomodulatory effects belongs to the epithelial cells, a type of epiblast-derived fetal stem cells which currently used for regenerative medicine and transplantation. These cells are collected by author-prepared faci...

Purpose The eye is an immune-privileged microenvironment that has adapted several mechanisms of immune regulation to prevent inflammation. One of these potential mechanisms is retinal pigment epithelial cells (RPE) altering phagocytosis in macrophages. Methods The conditioned media of RPE eyecups from eyes of healthy mice and mice with experimental autoimmune uveitis (EAU) were used to treat ...

In this study, possible paracrine factors in adipose tissue from lean and obese subjects were sought. Conditioned media were prepared by incubation in alpha minimum essential medium of adipocyte precursors derived from lean and massively obese subjects. Adipocyte-precursor-derived conditioned media from the obese stimulated replication of cultured rat perirenal adipocyte precursors by about fou...

Co-culture with glial cells and glia-conditioned media can induce blood-brain barrier properties in microvessel endothelial cells and protect against hypoxia-induced blood-brain barrier breakdown. We examined the effect of two types of glia-conditioned media on brain microvessel endothelial cell permeability and tight junction protein expression, and studied potential mechanisms of action. We f...

The adaptive responses in skin to ultraviolet (UV) radiation include increased cornification of keratinocytes and increased synthesis and distribution of melanin by melanocytes. The possible involvement of paracrine factors in the generation of these responses was studied in a novel two-stage culture model. Human melanocytes or keratinocytes were first irradiated or sham-irradiated and then the...

Fasting to postprandial transition requires a tight adjustment of insulin secretion to its demand, so tissue (e.g., skeletal muscle) glucose supply is assured while hypo-/hyperglycemia are prevented. High muscle glucose disposal after meals is pivotal for adapting to increased glycemia and might drive insulin secretion through muscle-released factors (e.g., myokines). We hypothesized that insul...

Mice, cell lines, retroviral vectors, cell culture, flow cytometry, immunostainings, teratoma formation and blastocyst injections were previously described in detail (Wernig et al., 2007; Meissner et al., 2007; Brambrink et al., 2008). Wnt3a conditioned media (Willert et al., 2003) and control conditioned media from parental L cells were generated according to standard protocols (ATCC), and use...
