The involvement of gangliosides in processes related to nerve regeneration and sprouting has been demonstrated recently. The type of interaction by which gangliosides may influence neuronal sprouting was investigated in the present work. Affinity-purified rabbit anti-GM1 antibodies were found to block the sprouting from dorsal root ganglia (DRG) of chicken embryo induced by nerve growth factor ...
The limited rewiring of the corticospinal tract (CST) only partially compensates the lost functions after stroke, brain trauma and spinal cord injury. Therefore it is important to develop new therapies to enhance the compensatory circuitry mediated by spared CST axons. Here by using a unilateral pyramidotomy model, we find that deletion of cortical suppressor of cytokine signaling 3 (SOCS3), a ...
the effects of desiccation and nacl and polyethylen glycol (peg) induced water potentials on rhizome bud sprouting of the perennial weed, glycyrrhiza glabra were investigated in separate laboratory experiments laid out in completely randomized designs. each treatment was replicated four times. the water potentials of nacl and peg used were 0, -0.4, -0.8, -1.2 and -1.6 mpa. desiccation experimen...
Potato tuber sprout results in nutrient loss and solanine production. Essential oils have been mentioned to reduce sprouting; however, they can easily evaporate decompose, thus restricting their application. In this paper, the inhibition effect of methyl salicylate (MeSA) as main component wintergreen essential oil on sprouting was evaluated, MeSA hydrogel prepared by using ionic gel method imp...
The density and architecture of capillary beds that form within a tissue depend on many factors, including local metabolic demand and blood flow. Here, using microfluidic control of local fluid mechanics, we show the existence of a previously unappreciated flow-induced shear stress threshold that triggers angiogenic sprouting. Both intraluminal shear stress over the endothelium and transmural f...
BACKGROUND AND AIMS Adventitious sprouting from the hypocotyle and roots in monocarpic herbs has been confirmed in previous experimental studies as a means to avoid bud limitation after severe injury in annual and biennial plants. Data regarding the role of adventitious sprouting in natural populations, however, were lacking. The aim of the present study was to assess whether adventitious sprou...
Some chronic pain conditions are maintained or enhanced by sympathetic activity. In animal models of pathological pain, abnormal sprouting of sympathetic fibers around large- and medium-sized sensory neurons is observed in dorsal root ganglia (DRGs). Large- and medium-sized cells are also more likely to be spontaneously active, suggesting that sprouting may be related to neuron activity. We pre...
Vascular sprouting is a key process-driving development of the vascular system. In this study, we show that neuropilin-2 (Nrp2), a transmembrane receptor for the lymphangiogenic vascular endothelial growth factor C (VEGF-C), plays an important role in lymphatic vessel sprouting. Blocking VEGF-C binding to Nrp2 using antibodies specifically inhibits sprouting of developing lymphatic endothelial ...
Increased expression of NGF after spinal cord injury induces sprouting of primary nociceptive axons. Exogenous application of NGF also results in extensive sprouting of these axons and causes chronic pain in uninjured animals. During development, semaphorin3A is thought to act as a repulsive guidance cue for NGF-responsive nociceptive afferents, restricting their projections to the superficial ...
Vascular development of the central nervous system and blood-brain barrier (BBB) induction are closely linked processes. The role of factors that promote endothelial sprouting and vascular leak, such as vascular endothelial growth factor A, are well described, but the factors that suppress angiogenic sprouting and their impact on the BBB are poorly understood. Here, we show that integrin αVβ8 a...
