Objective: This study aimed to evaluate the potential of combining allogeneic adipose-derived mesenchymal stem cells (ADSCs) with autologous concentrated growth factors (CGF) to enhance the repair of mandibular defects in rabbits.
Methods: Rabbit ADSCs were characterized using flow cytometry, identifying CD73, CD90, and CD105 as surface markers, while Alizarin Red Staining confirmed osteogenic differentiation, showing substantial mineralized deposits by day 21. A total of 24 New Zealand white rabbits were divided into four groups: BLANK (control group), CGF, ADSCs, and ADSCs/CGF.
Stem Cells Within Three-Dimensional-Printed Scaffolds Facilitate Airway Mucosa and Bone Regeneration and Reconstruction of Maxillary Defects in Rabbits.

Department of Otolaryngology-Head and Neck Surgery, Seoul St. Mary's Hospital, College of Medicine, The Catholic University of Korea, Seoul 06591, Republic of Korea.
: Current craniofacial reconstruction surgical methods have limitations because they involve facial deformation. The craniofacial region includes many areas where the mucosa, exposed to air, is closely adjacent to bone, with the maxilla being a prominent example of this structure. Therefore, this study explored whether human neural-crest-derived stem cells (hNTSCs) aid bone and airway mucosal regeneration during craniofacial reconstruction using a rabbit model.

Surg Infect (Larchmt)
January 2025
First Clinical Medical College, Ningxia Medical University, Yinchuan, China.
This study aims to compare the expression levels of tumor necrosis factor-alpha (TNF-α) and interleukin-1 beta (IL-1β) in osteoblasts infiltrated with H37Rv (H37Rv) and to understand the differential bone destruction in spinal tuberculosis (STB) versus spondylitis (BS). Primary osteoblasts were isolated and cultured from the cranial bones of 2-5 days old mice and characterized by alkaline phosphatase (ALP) staining and alizarin red staining (ARS). H37Rv and were cultured to the logarithmic phase, and transfection solutions were prepared.

Beijing Institute of Dental Research, Beijing Stomatological Hospital, School of Stomatology, Capital Medical University, Beijing, China.
Background: Low-intensity pulsed ultrasound (LIPUS) has been used as an effective noninvasive method for treating fractures and osteoarthrosis, but the application in the field of oral implantation is in its infancy. This study aimed to clarify the effect and mechanism of LIPUS on the osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) and implant osseointegration, and to provide an experimental basis for future clinical applications.
Methods: Dental implants were inserted into Wistar rat femurs, and LIPUS was performed for 4 weeks.
Attenuating Atherosclerosis through Inhibition of the NF-B/NLRP3/IL-1 Pathway-Mediated Pyroptosis in Vascular Smooth Muscle Cells (VSMCs).
Cardiovasc Ther
January 2025
Institute of Medicine, Hubei Key Laboratory of Diabetes, Hubei University of Science and Technology, Xianning, China.
Objective: We investigated the effects of resveratrol (Res) and MCC950 on the pyroptosis of vascular smooth muscle cells (VSMCs) and the potential pathway.
Methods And Results: Compared with the control (Con) group, the atherosclerosis (AS) group showed calcified nodules, which suggested that the calcification medium induced the calcification of VSMCs. VSMCs showed proliferative activity and significantly attenuated calcification under treatment with 10 mol/L Res.
