Primary osteogenic sarcomas of the breast are exceptionally uncommon. We describe such a case occurring in a 50 year-old woman who presented with a large painful mass in her left breast. Simple mastectomy of the left breast was performed. Microscopical and immunohistochemical findings established the diagnosis of primary osteogenic sarcoma. Similar to extremity osteosarcoma, adjuvant adriamycin and cisplatin based chemotherapy and external beam radiotherapy was given to the present case. She remained well 57 months later, without tumor recurrence. The current article made a literature search proving the rarity of this lesion type and discusses in detail the diagnostic implications and the treatment of this rare site tumor entity.

The periodontal ligament (PDL) is a connective tissue, and PDL cells have a potential to differentiate into cementoblasts, osteoblasts, and gingival fibroblasts. This study investigated whether transcription factor c-Myb could induce differentiation of PDL cells for periodontal regeneration. PDL cells were isolated from extracted teeth and cultured.

Purpose: This study aimed to evaluate the osteogenic performance of allograft particulate bone and cortical bone blocks combined with xenograft under bovine pericardium membranes, for treating different degrees of labial bone defects in the aesthetic zone.
Materials And Methods: Twenty-four patients with bone defects were divided into two groups based on defect severity (Terheyden 1/4 and 2/4 groups). The Terheyden 1/4 group received granular bone grafts alone, while the Terheyden 2/4 group received cortical bone blocks combined with granular bone grafts.
Icariin (ICA) serves as the primary biologically active compound in traditional Chinese medicine Epimedium, while Icariside II (ICSII) represents one of its gastrointestinal metabolites. Although ICA and ICSII have demonstrated osteogenic differentiation- promoting effects on BMSCs, there is limited literature comparing their effects and underlying mechanisms. This study aimed to compare the osteogenic effects of Icariin and Icariside II, along with their respective osteogenic mechanisms.

Bone defects restoration has always been an arduous challenge in the orthopedic field due to the limitations of conventional grafts. Bone tissue engineering offers an alternative approach by using biomimetic materials, stem cells, and growth factors that are able to improve the regeneration of bone tissue. Different biomaterials have attracted great interest in BTE applications, including the poly(3-hexylthiofene) (P3HT) conductive polymer, whose primary advantage is its capability to provide a native extracellular matrix-like environment.

Chemerin, an adipocyte-secreted adipokine, can regulate bone resorption and bone formation and is a promising therapy for postmenopausal osteoporosis. However, the effect of endogenous chemerin on intraosseous vascular remodeling in postmenopausal osteoporosis remains unclear. In this study, we investigated the effect of chemerin on osteogenesis formation and intraosseous vascular remodeling in ovariectomized Rarres2 knockout (Rarres2) mice.
