Figure Legend Snippet: TRPM8 channel expression in hBM-MSCs. (A) RT-PCR from total hBM-MSCs RNA. cDNA fragment corresponding to TRPM8 transcript (144 bp) in hBM-MSCs is shown. As controls we used HEK cells transfected with TRPM8 and non-transfected cells, respectively. RPL 27 (Name of the Ribosomal proteinL27, 120 bp) is the housekeeping gene ( n = 3). (B) Western blot detected TRPM8 protein in hBM-MSCs and cells transfected with TRPM8 (130 kDa). β-actin (45kDA) was used as a load control. As a negative control we used untransfected cells. (C) Percentage of TRPM8 total and membrane expression in hBM-MSCs and control cells transfection ( n = 3). (D) TRPM8 expression pattern in permeabilized hBM-MSCs (left panel) and control of unspecific secondary antibody binding (right panel) ( n = 4). The images presented in the figure shown confocal images of Alexa fluor 488 (TRPM8, green) and DAPI (blue).
Techniques Used: Expressing, Reverse Transcription Polymerase Chain Reaction, Transfection, Western Blot, Negative Control, Binding Assay

Maximum image volume projection of hBM-MSCs after double staining with the antibody TRPM8 conjugated with Alexa 488 and Mitotracker Red FM (colocalization index 0.03) (Overlap 0.36) (A) , Lisotracker Red (colocalization index 0.02) (overlap 0.49) (B) , and Alexa 647 calnexin (colocalization index 0.14) (Overlap 0.60) (C) . (D) Selected area for the colocalization analysis (perinuclear region). (E) Colocalization analysis ( n = 3) experiments.
Techniques Used: Double Staining
Figure Legend Snippet: hBM-MSCs express functional TRPM8 channels. (A,B) Currents evoked in response to a voltage pulse protocol. Current- voltage (IV) curves in whole cell configuration in hBM-MSCs cells before (control) and after the addition of menthol 500 μM and BCTC 10 μM ( n : 4). (Insert: Voltage step protocol). TRPM8 currents were calculated by subtracting the residual current after the addition of BCTC current from the current activated by menthol. (B) IV in response to a voltage ramp protocol in configuration of whole cell before (control, continues line) and after the addition of menthol 500 μM (dashed line) and BCTC 10 μM (dotted line) ( n = 4). The ramp protocol used for the acquisition of the records is indicated in the insert. (C) Current density (pA/pF) from hBM-MSC at −80 mV and +80 mV, before and after menthol addition. * P < 0.05. Data are mean ± SD ( n = 3).
Techniques Used: Functional Assay

![(A) RT-PCR for <t>trpm8</t> (236 bp) from cDNA extracted from stage 24 whole embryo or dissected spinal cord. +/− RT, in the presence or absence of the reverse transcriptase, respectively, during conversion of isolated mRNA into cDNA. (B) In situ hybridization for trpm8 in stage 24 embryos showing specific labeling in brain and spinal cord. (C) Western blot assays from egg, stage 24 wild-type whole embryo or from stage 40 whole larva, control morpholino (MO) or TRPM8-translation-blockingMO 1 (TRPM8-tbMO1) lysates. Predicted TRPM8 molecular weight [MW]: 132 kDa. Shown are representative examples of one of 3 independent experiments. β-tubulin was used as loading control. (D) Immunostained transverse section of stage 25 spinal cord (outlined). D, dorsal; V, ventral; scale bar, 20 μm; arrows indicate TRPM8 clusters in ventral neuron domains. NCAM labeling was used as counterstaining. (E) Stage 24 ventral spinal cord from wild-type embryos was Ca 2+ imaged at 1 Hz for 90 s. Either 100 μM (−)-menthol or vehicle (0.05% DMSO)was added after 35 s of imaging and recording continued for another 60 s. Images show a menthol-responsive ventral neuron before (left, control) and after (right) addition of (−)-menthol. Colored scale shows fluorescence intensity in arbitrary units. Traces show the changes in fluorescence for the indicated cell (arrow) in both trials. (F) Stage 24 ventral spinal cord from wild-type embryos was Ca 2+ imaged in 30-min intervals at cold (14.5°C) and warm (26.5°C) temperatures in the absence (vehicle, 0.1% DMSO) or presence of 10 μM AMTB, TRPM8 inhibitor. Scatterplots show changes in Ca 2+ spike frequency when switching temperatures in individual spinal neurons and geometric mean (black lines) from N = 3 ventral spinal cords per condition (n of neurons analyzed: DMSO, 62; AMTB, 71). Teal circles represent neurons with higher spike frequency at 14.5°C, magenta circles represent neurons with higher spike frequency at 26.5°C, and black circles represent neurons with no change in spike frequency across temperatures; ****p < 0.0001, comparison within treatments Wilcoxon matched-pairs signed rank, two-tailed test. (G) RT-PCR from cDNA collected from stage 46 larvae previously injected with 2.5 pmol standard control morpholino (Control-MO) or TRPM8-splicing-blocking morpholino (TRPM8-sbMO) shows that trpm8 mature transcript (349 bp) is not detected in TRPM8-sbMO animals. odc : ornithine decarboxylase (101 bp) as positive control.
