New regenerative treatment strategies are being developed for intervertebral disc degeneration of which the implantation of various cell types is promising. All cell types used so far require in vitro expansion prior to clinical use, as these cells are only limited available. Adipose-tissue is an abundant, expendable and easily accessible source of mesenchymal stem cells. The use of these cells...
Experiments were conducted at the Horticulture Research Farm of Horticulture Department, Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Salna, Gazipur during December, 2007 to May, 2009 to investigate the effect of bulb cutting and potting media on propagation of hippeastrum. The bulb cutting significantly influenced all the parameters except days required to first leaf eme...
In order to evaluate the effect of different planting seedbeds (stale and false) and application of Oxyfluorfen herbicide on yield, yield components and control of garlic weeds, a split-plot experiment was conducted based on a randomized complete block design (RCBD) with three replications in the cropping year 2020-2021 at Agricultural Sciences and Natural Resources University of Khuzestan. The...
Nuclear lamina alterations occur in physiological aging and in premature aging syndromes. Because aging is also associated with abnormal stem cell homeostasis, we hypothesize that nuclear envelope alterations could have an important impact on stem cell compartments. To evaluate this hypothesis, we examined the number and functional competence of stem cells in Zmpste24-null progeroid mice, which...
Bone morphogenic proteins (BMPs) and the Notch pathway regulate quiescence and self-renewal of stem cells of the subventricular zone (SVZ), an adult neurogenic niche. Here we analyze the role at the intersection of these pathways of Tis21 (Btg2/PC3), a gene regulating proliferation and differentiation of adult SVZ stem and progenitor cells. In Tis21-null SVZ and cultured neurospheres, we observ...
Abstract Strong, tall and healthy stems, as well as green background by means of leaves, are very important characters in marketing of cut flowers including Lily (Lilium). Also, in order to reuse the bulbs for next crop production, they should have enough stored materials and perimeter. This investigation was conducted to evaluate the effects of different media on some vegetative characters of...
most of the verbal constructions of harzani dialect have got inflectional affixes. the majority of the constructions are made up vy adding a specific verbal affix to the verbal stem (infinitive without infinitive marker). only a few number of them is formed by adding a verbal affix to the past participle of the verb. there are specific rules for the formation of different verbal types. there is...
We determined the embryonic origins of adult forebrain subventricular zone (SVZ) stem cells by Cre-lox fate mapping in transgenic mice. We found that all parts of the telencephalic neuroepithelium, including the medial ganglionic eminence and lateral ganglionic eminence (LGE) and the cerebral cortex, contribute multipotent, self-renewing stem cells to the adult SVZ. Descendants of the embryonic...
Adult neurogenic niches harbor quiescent neural stem cells; however, their in vivo identity has been elusive. Here, we prospectively isolate GFAP(+)CD133(+) (quiescent neural stem cells [qNSCs]) and GFAP(+)CD133(+)EGFR(+) (activated neural stem cells [aNSCs]) from the adult ventricular-subventricular zone. aNSCs are rapidly cycling, highly neurogenic in vivo, and enriched in colony-forming cell...
