Neurotrophins-Growth Factors Update

Our Neurotrophins and Growth Factor Antibodies and Recombinant Proteins help support a wide span of research areas. These areas include: neuroscience, immunology, cardiac disease research and cancer.

I would like to update you on recent publications highlighting use of some of these reagents: Aiko Sada, Kazuteru Hasegawa, Pui Han Pin, Yumiko Saga.

Images: Ngn3-Cre targets GFRA1-negative cells. (A-F): At P7, Rosa-YFP; Ngn3-Cre double transgenic testes were immunostained with the indicated markers. Most of YFP-positive spermatogonia (Ngn3-lineage cells) were not stained with GFRA1. Scale bar, 100 μm. (G): Quantification of YFP-positive cells per GFRA1-positive cells at P7 and 6 weeks (N=3).

Images: Mandibular nerve fibers were labeled by β-NGF which was administrated into the lower lip with CFA (A) or saline (F). On day 1 after β-NGF administration into the lower lip with CFA or saline, β-NGF-positive whisker pad or lower lip TG neurons defined by FG or DiI, respectively. B, G, β-NGF-positive TG neurons. C, H, DiI-labeled TG neurons. D, I, FG-labeled TG neurons. E, J, DiI- and FG-labeled β-NGF-positive TG neurons. Mandibular nerve fibers (K) and TG neurons (L) on day 1 after labeled BSA administration into the lower lip with CFA. Open arrow, β-NGF-positive nerve fibers. Arrow, DiI-labeled β-NGF-positive TG neurons. Arrowhead, FG-labeled β-NGF-positive TG neurons. Scale bar, 50 μm. M, Frequency of β-NGF-positive neurons in FG- or DiI-labeled TG neurons after CFA or saline injection into the lower lip (n = 5 in CFA-injected group; n = 4 in saline-injected group; Student's t test).
