introduction: satellite cells are known as the main regenerative cell type in skeletal muscles. our study established a modified digestion and preplating method for the isolation of slow or weak adherent cells for the enrichment of satellite cells. low-survival rate of these primary stem cells prompted us to address whether cell culture medium substitution might change cell viability status. me...
Muscle-derived stem cells (MDSCs) isolated from murine skeletal tissue by the preplate method have displayed the capability to commit to the myogenic lineage and regenerate more efficiently than myoblasts in skeletal and cardiac muscle in murine Duchenne Muscular Dystrophy mice (mdx). However, until now, these studies have not been translated to human muscle cells. Here, we describe the isolati...
BACKGROUND Ionizing irradiation of the esophagus results in development of esophagitis. In a mouse model, esophageal progenitor cells, isolated by either the side population (SP) sorting technique or a serial preplate technique, have been demonstrated to repopulate the irradiated esophagus of recipient mice. MATERIALS AND METHODS Esophageal progenitor cells (SP or preplate) as well as bone ma...
In the mutant mouse reeler, the tangential distribution of thalamocortical fibers is essentially normal, even though neurons of the cortical plate accumulate below the entire early-born preplate population (Caviness et al., 1998). This seems incompatible with the hypothesis that cells of the subplate (the lower component of the preplate in normal mammals) form an axonal scaffold that guides tha...
During corticogenesis, the earliest generated neurons form the preplate, which evolves into the marginal zone and subplate. Lrp12/Mig13a, a mammalian gene related to the Caenorhabditis elegans neuroblast migration gene mig-13, is expressed in a subpopulation of preplate neurons that undergo ventrally directed tangential migrations in the preplate layer and pioneer axon projections to the anteri...

Transgenic mice were generated to permit the targeted ablation of cortical preplate cells at the time they are born. In these mice, the 1.3 kb golli promoter of the myelin basic protein gene was used to drive the herpes simplex virus thymidine kinase (TK) transgene in cortical preplate cells. Heterozygous transgenic pairs were bred, and pregnant dams were treated with ganciclovir at embryonic d...
The time of origin, development, and morphology of neurons originating before the establishment of the cortical plate (preplate cells) were studied in the telencephalic vesicle of the rat from the embryonic day 10 (E10) to E15. The first postmitotic neurons settle superficial to the ventricular zone in the preplate at E12. We have observed mitotic figures in the preplate at E12 and E13, and reg...
As a step in defining the molecular environment for development of the mammalian cerebral cortex, we have used immunohistochemistry to analyze the distribution and remodeling of three major extracellular matrix (ECM) components, fibronectin, chondroitin sulfate proteoglycan (CSPG), and tenascin, during embryonic and early postnatal stages in the mouse. Fibronectin and CSPG are distributed throu...
The development of the layered cerebral cortex starts with a process called preplate splitting. Preplate splitting involves the establishment of prospective cortical layer 6 (L6) neurons within a plexus of pioneer neurons called the preplate. The forming layer 6 splits the preplate into a superficial layer of pioneer neurons called the marginal zone and a deeper layer of pioneer neurons called ...
