Figure Lengend Snippet: Characterization of SCAPs and DESCs. a Microscopic image of the apical buds from the lower incisors of 5-7-day-old C57BL/6 mice. b Primary mixed cell population. c Purified SCAPs exhibiting spindle-shaped morphology. d Multidirectional differentiation potential of SCAPs. Alcian Blue, Alizarin Red, and Oil Red O staining confirmed glycosaminoglycan deposition, mineralized nodule formation, and lipid droplet accumulation, indicative of chondrogenic, osteogenic, and adipogenic differentiation, respectively. e , f Flow cytometry analysis revealed CD24, CD133, and CD90 positivity, and CD45 negativity in SCAPs ( n = 3). The raw dot plots are presented in Supplementary Fig. S3. g Purified DESCs displaying cobblestone-like morphology. h Immunofluorescence imaging demonstrated positive K14 expression in DESCs (K14, green; DAPI, blue). i , j Flow cytometry analysis revealed CD29 and CD49f positivity, and CD90 negativity in DESCs ( n = 3). The raw dot plots are presented in Supplementary Fig. S3

Article Snippet: For SCAP analysis, cells were labeled with allophycocyanin (APC)-conjugated CD24 antibody (APC-65121, Proteintech, China, 1:300) as well as FITC-conjugated CD133 (11-1331-82, Thermo Fisher Scientific, USA, 1:500), CD90, and CD45 (MCD4501, Thermo Fisher Scientific, USA, 1:500) antibodies.
