MicroRNA changes of bone marrow-derived mesenchymal stem cells differentiated into neuronal-like cells by Schwann cell-conditioned medium.

Bone marrow-derived mesenchymal stem cells differentiate into neurons under the induction of Schwann cells. However, key microRNAs and related pathways for differentiation remain unclear. This study screened and identified differentially expressed microRNAs in bone marrow-derived mesenchymal stem cells induced by Schwann cell-conditioned medium, and explored targets and related pathways involved in their differentiation into neuronal-like cells.

[The labial and palatal bone thickness in 67 young adults with normal occlusion at the maxillary anterior teeth measured by cone-beam computed tomography].

Purpose: To investigate the labial and palatal bone thickness of the maxillary anterior teeth in normal young adults on different reference lines, in order to provide references for clinical treatment.

Methods: Sixty-seven eligible Han nationality young volunteers were scanned by cone-beam computed tomography (CBCT). The labial and palatal bone thickness and the labial bone morphology of the anterior teeth were measured after reconstruction.
