Tamoxifen is one of the most frequently used endocrine medications for the treatment of estrogen receptor-positive (ER + ) breast cancer (BC). Unfortunately, tamoxifen resistance (TR) brings more challenges to the clinical treatment, and the mechanisms of TR have not yet been fully clarified. HGF/c-Met is closely associated with cancer metastasis, but whether it is involved in TR remains unclear.

Deer antler blastema progenitor cells (ABPCs) are promising for regenerative medicine due to their role in annual antler regeneration, the only case of complete organ regeneration in mammals. ABPC-derived signals show great potential for promoting regeneration in tissues with limited natural regenerative ability. Our findings demonstrate the capability of extracellular vesicles from ABPCs (EVs) to repair spinal cord injury (SCI), a condition with low regenerative capacity.

Leaky and structurally abnormal blood vessels and increased pressure in the tumor interstitium reduce the infiltration of CAR-T cells in solid tumors, including triple-negative breast cancer (TNBC). Furthermore, high burden of tumor cells may cause reduction of infiltrating CAR-T cells and their functional exhaustion. In this study, various effector-to-target (E:T) ratio experiments are established to model the treatment using CAR-T cells in leukemia (high E:T ratio) and solid tumor (low E:T ratio).

Bone defects that exceed the critical defect value, resulting from fractures and diseases, are often difficult to heal. Although bone tissue engineering is a promising treatment for extensive osseous defects, orthopedic-implant-related infections increase the likelihood of failure. Bioactive glass (BG) has been widely used in the manufacture of artificial bone scaffolds, owing to its excellent biocompatibility and osteoinductivity.

Department of Cariology and Endodontics, Wuhan University & State Key Laboratory of Oral & Maxillofacial Reconstruction and Regeneration, Key Laboratory of Oral Biomedicine Ministry of Education, Hubei Key Laboratory of Stomatology, School & Hospital of Stomatology, Wuhan University, Wuhan, China.

Pulpotomy, which belongs to vital pulp therapy, has become a strategy for managing pulpitis in recent decades. This minimally invasive treatment reflects the recognition of preserving healthy dental pulp and optimizing long-term patient-centered outcomes. Pulpotomy is categorized into partial pulpotomy (PP), the removal of a partial segment of the coronal pulp tissue, and full pulpotomy (FP), the removal of whole coronal pulp, which is followed by applying the biomaterials onto the remaining pulp tissue and ultimately restoring the tooth.
