The expressions of ALX family genes in human neural crest cells and their derived cells / 中华整形外科杂志

ABSTRACT

Objective@#To compare the expressions of ALX gene family members (ALX1, ALX3, ALX4) in human embryonic stem cells (hESCs) and their differentiated neural crest cells (NCCs), as well as human mesenchymal stem cells (MSCs) and peripheral neurons derived from NCCs. The result provided a research foundation for understanding the expressions of ALX gene family in the process of NCCs differentiation.@*Methods@#The characteristics of hESCs, NCCs, MSCs and peripheral neurons were identified by RT-PCR, immunofluorescence staining and flow cytometry analysis. The expressions of ALX1, ALX3 and ALX4 were quantified by Real-time PCR.@*Results@#The expressions of ALX1 were significantly lower in MSCs than in NCCs (P < 0.05). However, the expression of ALX3 was significantly higher in MSCs than in hESCs, NCCs, peripheral neurons and osteoblasts (P < 0.05). The expressions of ALX4 were higher in MSCs, peripheral neurons and osteoblasts.@*Conclusions@#The expression profiles of different ALX genes in stem cells at different development stages are different, suggesting the regulation of ALX genes expressions is different in diverse cells.
