Project description:We have shown that removal of Lkb1 in chondorcytes results in enchondroma-like structure in postnatal mouse long bones. To furhter understand the role of Lkb1 in this process, we performed microarrrays to compare the transcriptional profile between control and conditional Lkb1 mutant (Col2a1-Cre; Lkb1c/c) chondrocytes. Postnatal day 30 mouse growth plate chondorcytes from control and mutant mouse femurs and tibiae were isolated for RNA extraction and hybridization on Affymetrix microarrays.
Project description:The TRPV4 skeletal disorders are characterized by short stature and scoliosis but the cellular mechanisms behind this phenotype are unclear. We isolated tibial and femoral cartilage growth plate chondrocytes from postnatal day 3 wild type and Col2a1-Cre driven Trpv4 p.R594H conditional knock-in mice, which models the phenotype, and analyzed differential expression patterns using single cell RNA-seq.

Project description:Osteogenesis Imperfecta is characterized by short stature however the cellular mechanisms behind this phenotype are unclear. We isolated tibial and femoral cartilage growth plate chondrocytes from postnatal day 5 wild type and Aga2 (a model of OI) mice and analyzed differential expression patterns using single cell RNA-seq
Project description:Longitudinal bone growth depends upon the execution of an intricate series of cellular activities by epiphyseal growth plate chondrocytes. In order to better understand these coordinated events, microarray analysis was used to compare gene expression in chondrocytes isolated from the proliferative and hypertrophic zones of the avian growth plate. In this experiment we compared pooled samples of proliferative and hypertrophic chondrocytes isolated from the chick growth plate. The expression of 745 genes was found to differ 3-fold or greater at the 0.05 level of probability.
Project description:Human growth plate chondrocytes were isolated from the distal femoral growth plate from a single adolescent undergoing epiphysiodesis. Cell were isolated and grown in monolayers, long term. Cells were replated and cultured in 0.5% or 20% serum. Keywords: parallel sample
Project description:Single cell transcriptomic profiling of hPSC-derived articular and growth plate chondrocytes during directed differentiation protocols and cells isolated from the epiphysis and growth plate of the human fetal femur at E59
Project description:Human growth plate chondrocytes were isolated from the distal femoral growth plate from 3 different adolescents undergoing epiphysiodesis. Cell were isolated and grown in monolayers, long term, in 20% serum. Cells were replated and cultured 48 h in 0.5% serum. Keywords: repeat sample
