The design of natural hybrid biomaterial to promote osteogenic differentiation, collagen i and II expression and relief of musculoskeletal pains: Bone tissue-engineering applications (in-vitro and clinical studies)

Abstract

This research aimed to fabricate a natural hybrid biomaterial and assess its physicochemical/biological properties to study the role of the therapeutic biomaterial in the growth of human monocytes, synoviocytes, chondrocytes, expression of type-I/II collagen, and osteogenic differentiation for bone tissue engineering applications, as well as to assess effects of bio-ointment derived from this biomaterial on relief of musculoskeletal pains. Hence, an oily formula [turmeric:ginger:chili pepper:rose oils (1:1:1:1w/w)] was mixed with the base oil [sesame:black seed:olive oils (1:0.4:0.6w/w)] in 3 wt ratios of 1:6(H1), 1.5:5.5(H2), and 2:5(H3). Accordingly, H2 indicated a better performance in cell growth and decrease of inflammatory mediators and led to the highest expression of osteoblastic genes of RUNX2, OCN, and OPN, as well as collagen I and II (COL1A1,COL2A) respectively 1.3-fold, 1.7-fold, and 1.4-fold, as well as %87 % and ∼ 60 % higher than H1, and ∼ 2-fold, 2.1-fold, and 3.4-fold, and ∼ 19 % and ∼ 16 % higher than H3. A clinical study on H2 was also performed on 50 patients with musculoskeletal pains. H2-based bio-ointment could relieve pain in less than 10 min for 40 % of patients and after 30 min from use for 35 %. Moreover, the analgesia period for 60 % and 36 % of patients lasted for longer than 3 h and between 2 h and 3 h, respectively. 76 % also stated that bio-ointment possesses stronger effects than other treatments along with moderate warming functions. Finally, although 6 % of patients reported mild effectiveness in pain relief, 92 % of users stated this therapeutic method has resulted in more effects on their pain relief and damaged organ performance recovery.
