Fig. 8From: Pure platelet-rich plasma promotes semaphorin-3A expression: a novel insight to ameliorate intervertebral disk degeneration in vitroGraph in a schematic. The isolation and culture of rat NPCs and IVDs. The next step was to introduce IL-1β to cause degeneration. L-PRP and P-PRP, later employed to treat IL-1β-induced degenerative IVDs and NPCs, were synthesized using two-step centrifugation techniquesBack to article page
