Wharton's jelly is not only one of the most promising tissue sources for mesenchymal stem cells (MSCs) but also a source of natural growth factors. To prove that we can get both natural growth factors and MSCs from Wharton's jelly, we compared cellular characteristics and the level of basic fibroblast growth factor (bFGF) from samples using the explant culture method to those derived from the t...

PURPOSE. To validate an established adult organotypic retinal explant culture system for use as an efficient medium-throughput screening tool to investigate novel retinal ganglion cell (RGC) neuroprotective therapies. METHODS. Optimal culture conditions for detecting RGC neuroprotection in rat retinal explants were identified. Retinal explants were treated with various recognized, or purported,...

Six tetraploid Alstroemeria clones were micropropagated by rhizome multiplication, a system whereby the shoots were cut off from the rhizome and discarded. In a three-week subculture interval, the average rhizome multiplication rate for all genotypes was 2.3. In one selected genotype the discarded shoots were used to initiate another micropropagation system: the leafy explant micropropagation s...

Human colon tissue explant culture provides a physiologically relevant model system to study human gut biology. However, the small (20-30 mg) and complex tissue samples used present challenges for monitoring tissue stability, viability, and provision of sufficient tissue for analyses. Combining molecular profiling with explant culture has potential to overcome such limitations, permitting inter...

to produce embryogenic callus and somatic embryos, tendril explants were collected and cultured in ms medium supplemented with various concentrations of hormones. after one month most of explants produced callus. the highest percent of embryogenic callus obtained in ms medium supplemented with 4.5 µm bap and 1µm 2,4-d. production of somatic embryos was depended on genotype and medium. yaghouti ...

Automation of cell culture would facilitate stable cell expansion with consistent quality. In the present study, feasibility of an automated closed-cell culture system "P 4C S" for an embryoid body- (EB-) explant outgrowth culture was investigated as a model case for explant culture. After placing the induced pluripotent stem cell- (iPSC-) derived EBs into the system, the EBs successfully adher...

Explant of trigeminal ganglia neurons in adult rats induces perineuronal glial proliferation of primarily satellite cells as opposed to Schwann cells. This proliferation begins at 15 h after explant culture and by 27 h there is a significant increase in glial proliferation as measured by scintillation counts of [3H]thymidine. Blocking protein synthesis between 0 and 3.5 h after explant culture ...

Several studies have shown that decidual tissue produces soluble factors which can mediate a variety of immunosuppressive activities. In order to assess whether prostaglandin E2 (PGE2) was present in supernatants produced by explant culture of 10 human specimens of first trimester decidua. The effect of the supernatants from the two different series (with and without indomethacin treatment) of ...

INTRODUCTION In modern medicine and dentistry the use of biomaterials is a fast developing field of increasing interest. Especially in dentistry the interaction between biomaterials like implant materials and the soft tissue in the oral cavity is in the focus of daily research. In this context the high importance of testing materials and their surfaces concerning their biocompatibility towards ...
