幹細胞療法被認為是治療退行性骨關節疾病（OA）的潛在方法。然而，幹細胞的最佳劑量尚不清楚，這限制了其臨床應用。本文探討了不同劑量幹細胞療法對OA的劑量效應關係，為確定最佳劑量策略提供了見解。
幹細胞劑量對軟骨再生和疼痛緩解的影響
幹細胞劑量對軟骨再生和疼痛緩解有顯著影響。低劑量幹細胞可能有助於軟骨基質的合成，而高劑量幹細胞則促進軟骨細胞的增殖和分化。此外，高劑量幹細胞已被證明能更有效地減輕疼痛，這可能是由於其對炎症和神經病變的抑制作用。
劑量依賴性與治療反應的相關性
幹細胞劑量和治療反應之間存在劑量依賴性關係。低劑量幹細胞可能產生亞閾值效應，而高劑量幹細胞則導致過度生長或異位形成。因此，確定一個最佳劑量至關重要，既能提供治療益處，又能最小化不良事件的風險。
