  3. Zinc borate

Zinc borate is a bioactive inorganic substance with properties including osteogenic induction, pro-angiogenesis, antioxidation, antimutagenesis and cytotoxicity. In the field of bone tissue engineering, Zinc borate is often incorporated into chitosan scaffolds. By releasing zinc ions and borate ions, Zinc borate induces the differentiation of human dental pulp stem cells into osteoblasts, upregulates the expression of bone-related genes and promotes calcium deposition. Zinc borate also promotes angiogenesis by upregulating key factors such as vascular endothelial growth factor. Zinc borate exhibits antioxidant capacity to scavenge free radicals, and can specifically reduce mutagenicity under specific conditions. Zinc borate reduces the survival rate of mouse fibroblasts, but it can still be used in studies related to bone tissue engineering.

In Vitro

When zinc borate (1.0% (w/v); 7-21 d) is loaded on chitosan scaffolds, it supports stem cells from human exfoliated deciduous teeth (SHEDs), significantly improving cell viability, with absorbance values at 570 nm of approximately 0.29, 0.41, and 0.57, respectively; it also significantly upregulates ALP activity[1].
Zinc borate (1.0% (w/v); 7-21 d) incorporated into chitosan scaffolds supports SHEDs, significantly upregulating the expression of osteogenesis-related genes (Runx2, OPN, and OCN) and angiogenesis-related genes (VEGF, Ang-1) during osteogenic differentiation[1].
Zinc borate (1 mg/mL; 30 min) exhibits low DPPH free radical scavenging activity in cell-free assays, with an inhibition rate of 13.50% at 1 mg/mL[2].
Zinc borate (0.04-0.2 mg; 72 h) exhibits low antimutagenic activity against 4-NPD-induced mutagenicity in Salmonella typhimurium strain TA98, but shows no antimutagenic activity against sodium azide-induced mutagenicity in strain TA100[2].
Zinc borate (0.3-76.19 μg/mL; 24-72 h) exhibits cytotoxicity against mouse fibroblast L929 cells, with an IC50 value of 40.70 μg/mL at 24 h and 32.93 μg/mL at 72 h[2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
