Tyrosine hydroxylase–positive populations were gener- ated from undifferentiated HUMSCs by a three-step in vitro differ- entiation method. Abbreviations: DMEM, Dulbecco’s modified Ea- gle’s medium; FBS, fetal bovine serum; FGF, fibroblast growth factor; HUMSC, human umbilical mesenchymal stem cell; NCM, neuronal-conditioned medium; Shh, sonic hedgehog.

Article Snippet: In stage 3, cells were supplemented with NCM or 10% FBS-DMEM in the presence of the murine N-terminal fragment of sonic hedgehog (SHH) (500 ng/ml, 461-SH, R&D Systems Inc., Minneapolis, http://www.rndsystems.com) and murine FGF8 isoform b (FGF8) (100 ng/ml, 423-F8, R&D Systems Inc.) for 3, 6, 9, or 12 days.

Figure Lengend Snippet: Figure 2. HUMSC differentiation into dopaminergic, norepinephrine, and GABAergic neurons in vitro. (A): Photomicrographs showing TH immunocytochemistry of cultured HUMSCs. The cells expressed TH after incubation with NCM for 6 days and then SHH and FGF8 in DMEM for 3 days. In addition to TH-positive neurons, DBH-positive (B) and GAD-positive (C) neurons were detected. Human-specific nuclear antigen are in green, and DBH and GAD are in red. Arrows indicate cells stained positively for TH, DBH, or GAD. Scale bar 100 m. (D): Histograms showing the percentage of TH-positive cells after incubation with NCM, SHH, and FGF8. (Results represent the mean standard error from three different experiments. At least 200 cells were counted from 10 randomly selected microscopic fields in each experiment. Statistics consisted of one-way ANOVA followed by the LSD test; *statistical difference at p .05 compared with NCM-only group.) (E): TH expression in cultured cells by Western blotting. The molecular weight of rat and human TH were 60 and 68 kDa, respectively. Rat SN served as positive control. (F): Dopamine concentration in culture medium after HUMSCs were treated with NCM, SHH, and FGF8. (Results represent the mean standard error from three different experiments. Statistics consisted of one-way ANOVA followed by the LSD test; *statistical significance at p .05 compared with DMEM and NCM-only groups.) Abbreviations: ANOVA, analysis of variance; DBH, dopamine--hydroxylase; DMEM, Dulbecco’s modified Eagle’s medium; FGF, fibroblast growth factor; LSD, least-significant difference; HUMSC, human umbilical mesenchymal stem cell; NCM, neuronal-conditioned medium; Shh, sonic hedgehog; SN, substantia nigra; TH, tyrosine hydroxylase.

Figure Lengend Snippet: Figure 5. Rotation behavior in response to amphetamine tested at 1, 2, 3, 4, and 5 months after lesion. A significant decrease in the number of amphetamine-induced turning was seen in animals with grafted cells treated with NCM SHH FGF8 (, n 6) compared with control (lesion-only) animals (F, n 12) and lesioned animals that received grafted cells treated with NCM (E, n 12). Statistics consisted of two-way ANOVA followed by the LSD test. (* Significant difference at p .05 between NCM SHH FGF8-treated group compared with the control and NCM groups at the same time point. # Significant difference at p 0.05 between the control and NCM groups over 1-month intervals.)

Figure Lengend Snippet: Expression of Shh mRNA and SHH-Nter protein in the developing cortex. Expression of Shh transcripts detected by in situ hybridization and RNAscope in median (A) and caudal (B) E14.5 brain sections. In situ hybridization of forebrain sections with an antisens Shh probes shows strong expression of Shh mRNA in the ventral forebrain [MGE and MGE/LGE/septum boundary (A1), CGE (B1)], in the zona limitans (ZLI) of dorsal thalamus and the border of the 3 rd ventricle (B1). RNAscop of forebrain sections further confirmed the strong expression of Shh mRNA in the MGE/septum boundary that express Lhx-6 mRNA (a transcription factor expressed in post-mitotic interneurons in the ventral brain) (A2) and the CGE (B2). At higher magnification, Shh mRNA fluorescence (in green) labels a subpopulation of interneuron cell bodies (in red) in the MGE/septum boundary, in the subventricular zone of the MGE and in more dispersed cells in the MGE mantle (A2) and in the lateral and dorsal cortex (arrows, C1 and C2). Among Shh mRNA expressing cells in the cortex, some are principal glutamatergic cells (arrowhead, C1) and only few cIN express the transcript (C3). The graph represents the mean ± SEM in the IZ-CP layers and MZ layer. Expression of SHH-Nter protein in E14.5 median brain sections (D). Representative images are captured with epifluorecence (D1) and confocal microscop (D2). Confocal images are a merged stacks of 10 images and enlargment of pictures are shown. SHH expression is detected in blood vessels and in brigth dots all over the cortical neuropile. At the PSB and in the lateral part of the LGE, SHH-Nter is detectable in brigth elements aligned along the ventricular/subventricular axis.
