Research Question: To investigate the underlying mechanisms driving the opposing effects of transforming growth factor-beta 1 (TGFβ1) on the proliferation of control (CESCs) and ectopic (EESCs) endometrial stromal cells.
Design: Cell proliferation assays (CCK-8 and colony formation) were employed to assess the effects of TGFβ1 on CESC and EESC proliferation. An immortalized human endometrial stromal cell line (HESC) was used to elucidate the mechanisms behind cytostatic effect of TGFβ1 and the potential role of cyclooxygenase (COX)-2 in mediating the modulation of TGFβ1 signaling.

Introduction: Osteoarthritis (OA) is a degenerative joint disease that can affect the many tissues of the joint. There are no officially recognized disease-modifying therapies for clinical use at this time probably due to a lack of complete comprehension of the pathogenesis of the disease. In recent years, emerging regenerative therapy and treatments with stem cells both undifferentiated and differentiated cells have gained much attention as they can efficiently promote tissue repair and regeneration.

Inflammatory is a crucial part of the immune system of body protect it from harmful invaders, such as bacteria, viruses, and other foreign substances. In this study, the effects of chloroform extract of fermented (CEFV) on lipopolysaccharide (LPS)-induced inflammatory response in RAW264.7 macrophages were investigated.

Prostaglandin E2 (PGE-2) is synthesised by cyclooxygenase-2 (COX-2) and microsomal prostaglandin E synthase 1 (mPGES-1). PGE-2 exhibits pro-inflammatory properties in inflammatory conditions. However, there remains limited understanding of the COX-2/mPGES-1/PGE-2 pathway in Angiostrongylus cantonensis-induced meningoencephalitis.
