This study aimed to identify the possible function and the molecular mechanism of hsa_circ_0007334 in human bone marrow mesenchymal stem cells (hBMSCs) osteogenic differentiation. The level of hsa_circ_0007334 was detected by means of quantitative real-time polymerase chain reaction (RT-qPCR). Alkaline phosphatase (ALP), RUNX2, osterix (OSX), and osteocalcin (OCN) were monitored to analyze the degree of osteogenic differentiation under routine culture or under the control of hsa_circ_0007334. The proliferation of hBMSCs was tested with a cell counting kit-8 (CCK-8) assay. The migration of hBMSCs was tested using the Transwell assay. Bioinformatics analysis was used to predict the possible targets of hsa_circ_0007334 or miR-144-3p. Dual-luciferase reporter assay system was used to analyze the combination between hsa_circ_0007334 and miR-144-3p. Hsa_circ_0007334 was upregulated in osteogenic differentiation of hBMSCs. Osteogenic differentiation increased by hsa_circ_0007334 <i>in vitro </i>was confirmed with levels of ALP and bone markers (RUNX2, OCN, OSX). hsa_circ_0007334 overexpression promoted osteogenic differentiation, proliferation, and migration of hBMSCs, and knockdown of hsa_circ_0007334 has the opposite effects. miR-144-3p was identified as the target of hsa_circ_0007334. The targeting genes of miR-144-3p are involved in osteogenic-differentia-tion-related biological processes (such as bone development, epithelial cell proliferation, and mesenchymal cell apoptotic prosess) and pathways (including FoxO and VEGF signaling pathway). Hsa_circ_0007334, therefore, presents itself as a promising biological for osteogenic differentiation.
