ABSTRACT Regeneration as an adult developmental process is in many aspects similar to embryonic development. Although studies point out similarities and differences, no large-scale, direct functional comparative analyses between development regeneration of a specific cell type or structure one animal exist. Here, we use the brittle star Amphiura filiformis characterise role FGF signalling pathw...

Tef [Eragrostis tef (Zucc.) Trotter] is the major cereal crop in the Horn of Africa particularly in Ethiopia where it is staple food for about 50 million people. Its resilience to extreme environmental conditions and high in nutrition makes tef the preferred crop among both farmers and consumers. The efficiency of in vitro regeneration plays significant role in the improvement of crops. We inve...

punicagranatum cv. malassaveh is one of the most desirable commercial cultivars in iran. in thisstudy some experiments were conducted to introduce the best hormonal treatments for directadventitious shoot regeneration from mentioned cultivar via cotyledonary explants. for thispurpose, both liquid and agarmurashige and skoog (1962) (ms) medium supplemented with baat 2, 4.5, 9, 13 μm alone and in...

Integrin activation is essential for creating functional transmembrane receptors capable of inducing downstream cellular effects such as cell migration, cell spreading, neurite outgrowth and axon regeneration. Integrins are bidirectional signalling molecules that mediate their effects by 'inside-out' and 'outside-in' signalling. This review will provide a detailed overview of integrin activatio...

due to climate changes in recent years, in order to attain comfort and convenience, demands for heating, ventilating, and air conditioning (hvac) systems have been increased around the world, which has led to increases in emissions and power. desiccant cooling systems (dcss) are designed and built to reduce moisture and power consumption, create comfortable conditions for people in a building, ...

After partial hepatectomy, hepatocytes proliferate to restore mass and function of the liver. Macrophages, natural killer (NK) cells, natural killer T (NKT) cells, dendritic cells (DC), eosinophils, gamma delta T (γδT) cells, and conventional T cells, as well as other subsets of the immune cells residing in the liver control liver regeneration, either through direct interactions with hepatocyte...

The close apposition of osteoblasts and chondrocytes in bone and their interaction during bone development and regeneration suggest that they may each regulate the other's growth and differentiation. In these studies, osteoblasts and chondrocytes were co-cultured in vitro, with both direct and indirect contact. Proliferation of the co-cultured chondrocytes was enhanced using soluble factors pro...

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...
