the present work developed an efficient plant regeneration and propagation system via direct organogenesis for morinda officinalis how., a valuable endangered medicinal plant. the effects of explant types on shoot induction, plant growth regulators on shoot proliferationand elongation and the subsequent rooting ability of shoots were examined. among the various types of explant, direct shoot pr...

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 ...

In this study, we tried explant method and a combination of explant-enzymatic method for the extraction of Mesenchymal Stem Cells from ovine umbilical cord tissue wharton’s jelly. The isolated and culture expanded cells expressed strong alkaline phosphatase activity and they were shown to form colonies. The Mesenchymal Stem Cells showed positive for CD44 and negative for CD34 surface markers by...

The present study was carried out to investigate micropropagation possibility and determine the optimal medium composition and plant growth regulators (PGRs) combinations under in vitro conditions. The cotyledon and epicotyl explants obtained from 1 month old in vitro grown seedlings were used in MS medium containing BA (0.1, 0.2, 0.5, 1, 2 and 3 mg-1) and TDZ (0.1, 0.2, 0.5, 1, 2 and 3 mg-1) e...

Hairy root induction in plants has affected by many factors including type, age of explant and bacterial strain. In the present study, the effects of bacterial strains (A4, C58, 15834 and GM), two concentrations (OD600= 0.5 and 1) and two explants (leaves and stems) in hairy root induction of C. blumei</...

BACKGROUND Idiopathic pulmonary fibrosis (IPF) is a fatal lung disease with no known effective therapy. It is often assumed, but has not been objectively evaluated, that pulmonary inflammation subsides as IPF progresses. The goal of this work was to assess changes in the degree of inflammatory cell infiltration, particularly lymphocytic infiltration, over the duration of illness in IPF. METHO...

PURPOSE To describe the phenotypic characteristics of a limbal epithelial cell sheet outgrowth from a limbal explant cultured on amniotic membrane. METHOD Immunofluorescent staining and confocal microscopy were used to examine the expressions of p63, Ki-67, keratins 3 and 14, connexin 43, and the integrin alpha6/beta4 and alpha3/beta1 subunits in corneal and limbal tissues in a limbal explant...

The medium pH level of plant tissue cultures has been shown to be essential to many aspects of explant development and growth. Sensitivity or tolerance of medium pH change varies according to specific requirements of in vitro individual species. The objectives of this study are to 1) determine medium pH change over time in storage conditions and with presence of explants, 2) evaluate the effect...

Cultured embryonic and adult skeletal muscle cells have a number of different uses. The micro-dissected explants technique described in this chapter is a robust and reliable method for isolating relatively large numbers of proliferative skeletal muscle cells from juvenile, adult or embryonic muscles as a source of skeletal muscle stem cells. The authors have used micro-dissected explant culture...
