To explore the potential for in vitro rapid regeneration of Sainfoin (Onobrychis sativa), different concentrations of 6Benzylaminopurine (BAP), 1-naphthaleneacetic acid (NAA) and BAP combined with Indole-3-butyric acid (IBA) were evaluated for their effects on the induction of somatic embryos from leaf, stem and root explants. Different explants were cultured on MS medium supplemented with vari...

Dendritic/axonal growth has been examined in long-term organotypic neocortical explants taken from neonatal rat pups and grown either as isolated slices or as co-cultures. The quantitative light microscopic measurement of dendritic and axonal branching patterns within both types of explants was carried out on Golgi-stained materials. Spontaneous bioelectric activity (SBA) was blocked within bot...

agrobacterium rhizogenes (pri), a causative agent of hairy root disease, effectively induces hairy root formation in a variety of plant species. in our study four bacterial strains ar15834, a4, 9435 and c318 and three explants types leaf, stems and roots, were examined. hairy roots were induced from roots, stems and leaf explants. the highest transformation efficiency of 77% was achieved by usi...

Shoot multiplication of Bupleurum distichophyllum was achieved from the nodal and shoot tip explants of mature plants using MS with different concentrations and combinations of growth regulators. Maximum explant response was from axillary shoots and the highest number of shoots per explant was obtained on MS fortified with 1.0 mg/l BAP. The highest degree of axillary shoot proliferation was fou...

To understand in situ behavior of osteocytes, we characterized a model of osteocytes in their native bone matrix and demonstrated real-time biologic activity of osteocytes while bending the bone matrix. Using 43 male Sprague-Dawley rats, dumbbell-shaped explants were harvested from stainless steel femoral implants after 6-12 weeks and incubated in culture medium or fixed. Sixteen specimens were...

Lilium ledebourii (Baker) Boiss. (Liliaceae) is a critically endangered lily species native tonorthern Iran, where it is protected by law. In order to develop a cost effective method for largescalepropagation, the effects of three culture systems (solid, liquid and temporary immersion)and two types of cytokinins [6-Benzyladenine (BA) and Thidiazuron (TDZ)] were studied onthe in vitro plant rege...
