乳矩阵衍生物 (EMD) 可能抵消双酸盐 (BP) 对骨细胞的副作用,可能有助于治疗与药物相关的下巴骨硬化 (MRONJ). 需要进一步的研究来确认其临床有效性.
科学领域:
- 生物材料科学 生物材料科学
- 口腔和牙面部外科手术
- 细胞生物学 细胞生物学
背景情况:
- 双酸盐 (BPs) 抑制骨代谢,这是与药物相关的骨硬化 (MRONJ) 的主要原因.
- 乳矩阵衍生物 (EMD) 通过刺激生长因子,促进牙周组织再生.
研究的目的:
- 研究EMD的潜力,以逆转BP对人类胎儿骨质母细胞 (hFOB) 和MG63细胞的不良影响.
- 评估EMD对细胞活力,细胞亡,迁移,基因表达和BP治疗骨质母细胞中的蛋白质合成的影响.
主要方法:
- 治疗hFOBs和MG63细胞的zoledronate (Zol),一种BP,有和没有EMD.
- 评估细胞活力,细胞灭亡率和细胞迁移.
- 对性酸酶 (ALP),骨质素 (OC) 和核因子卡帕-B连接体 (RANKL) 受体激活剂的基因表达的分析.
- 测量OC,巨细胞殖民地刺激因子 (M-CSF),骨蛋白 (BSP) 和1型原蛋白 (COL1) 的蛋白质水平.
主要成果:
- EMD减轻了Zol对细胞活力和迁移的抑制作用,同时增加了这些参数.
- EMD 降低了 Zol 诱导的亡率.
- EMD逆转了Zol诱导的ALP,OC和RANKL在hFOB中的基因表达下降,以及MG63细胞中的ALP和BSP.
- 埃姆迪恢复了OC,M-CSF,BSP和COL1的抑制蛋白质水平.
结论:
- EMD显示出减轻双酸盐对骨质母细胞造成的有害影响的潜力,改善细胞存活,迁移和关键骨相关分子的表达.
- 虽然EMD表现出修复作用,但骨质细胞行为的完全正常化并未实现,因此需要进一步进行体内研究,以确定MRONJ在预防和治疗中的临床适用性.

Osteoclasts in Bone Remodeling
Essential Minerals for Bone Health
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

Role of Vitamins in Maintaining Bone Health
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
