Olfactory Ensheathing Cells (OECs) ensheathe unmyelinated olfactory axons and exhibit antigenic and morphological characteristics both of astrocytes and of Schwann Cells (SCs). As a matter of fact they express an astrocyte-specific marker (GFAP) and low-affinity p75 nerve growth factor receptor (p75 NGFr), S100, as well as adhesion molecules such as laminin and N-CAM like SCs. Immunocytochemica...

BACKGROUND The aim of this study was to evaluate the site-specific immunoregulatory mechanisms against viral infection in human Fallopian tubes. METHODS We therefore investigated the effects of double-stranded RNA (dsRNA) on the production of interleukin (IL)-6, IL-8 and granulocyte chemotactic protein-2 (GCP-2) by cultured oviductal epithelial cells (OECs) using enzyme-linked immunosorbent a...

Olfactory ensheathing cells (OECs) play an important role in the continuous regeneration of the primary olfactory nervous system throughout life and for regeneration of olfactory neurons after injury. While it is known that several individual OEC subpopulations with distinct properties exist in different anatomical locations, it remains unclear how these different subpopulations respond to a ma...

Successful nerve regeneration after nerve trauma is not only important for the restoration of motor and sensory functions, but also to reduce the potential for abnormal sensory impulse generation that can occur following neuroma formation. Satisfying functional results after severe lesions are difficult to achieve and the development of interventional methods to achieve optimal functional recov...

The objective of this study was to establish a primary culture of omasal epithelial cells (OECs) derived from dairy calves and to characterize its function in small peptide absorption. Bovine omasal tissues were obtained from newborn Chinese Holstein calves and digested with a 2.5% trypsin solution to obtain OECs. The isolated cells were later cultured in DMEM containing 10% fetal bovine serum,...

background: the cells of mammalian female reproductive tract have been widely used for in vitro fertilization (ivf). this study was designed to study the effects of oviductal epithelial cells (oecs) and their conditioned medium during ivf on subsequent embryonic development and the relative abundance of zygote arrest 1 (zar1) transcript in ovine zygotes. methods: the in vitro matured ovine oocy...

BACKGROUND Two types of cells are cultured from the human peripheral blood, early endothelial progenitor cells (EPCs) and outgrowth endothelial cells (OECs), as previously reported. Here, we further characterize these cells, especially with respect to their different origins and functions both in vitro and in vivo. We also investigated whether the combination of these different cell types shows...

This study aimed to examine olfactory mucosal changes in a rat model of acute rhinosinusitis and to determine how acute rhinosinusitis induces dysosmia. Total 100 rats were divided into the experimental (N = 80) and control (N = 20) groups. An acute rhinosinusitis model was established in the experimental rats. From the experimental group, 20 rats each were sacrificed at 1, 2, 3, or 4 weeks. Th...

Cell transplantation is a promising strategy to promote CNS repair and has been studied for several decades with a focus on glial cells. Promising candidates include Schwann cells (SCs) and olfactory ensheathing cells (OECs). Both cell types are thought to be neural crest derived and share many properties in common, although OECs appear to be a better candidate for transplantation by evoking le...
