Critical to tendon tissue engineering is the induction and guidance of stem cells towards the tendon phenotype.
In both vertebrates and invertebrates, induction and guidance of cell migration towards a target are achieved by the coordinated action of several growth factor signalling pathways.
Much like the dual involvement of morphogens in early cell fate induction and axon guidance, many guidance-related molecules continue to play active roles in controlling the location, number, shape, and strength of neuronal synapses during development and throughout the lifetime of the organism.
Mohanty, S., Sharma, M., Panicker, M. & Gupta, P. Controlled induction, enhancement, and guidance of neuronal growth cones by use of line optical tweezers.
TPVB was performed under ultrasound guidance before induction of general anesthesia by administering 20-ml 0.375 or 0.5%% ropivacaine in one or two intercostal spaces between T2/3 and T4/5.
Induction and inductance.
This review presents a pro/con case for using etomidate in hemodynamically unstable critically ill patients and provides guidance for alternative induction techniques and when the use of etomidate might be justified despite these concerns.
The correlation between stimulation of cells with chemoattractants and bleb formation (e.g. [ 35,36]), points at an instructive role of guidance cues in bleb induction.
Follicles were retrieved individually by aspiration 35 36 h after ovulation induction under neuroleptic anaesthesia and vaginal ultrasound guidance without flushing of follicles.
In addition it was successfully used for providing guidance to the determination of optimal induction time.
The implant procedures were all performed under general anaesthesia (thiopentone for induction; halothane/nitrous oxide inhalation for maintenance) using fluoroscopic guidance.
