3WJ-BMSCapt/M2-Exos

a3wj-Cholesterol

b3wj-BMSCaptamer

c3wj-Alexa 647

Drug

BMSC

Modification of M2-Exos enhances their targeting to BMSCs

In vitro, targeting BMSCs more effectively enhances their proliferation, migration, and osteogenic differentiationIn vivo, it stimulates callus formation, increases bone volume/total volume (BV/TV), bone mineral density (BMD), and trabecular number (Tb. N), reduces trabecular separation (Tb. Sp), promotes new bone formation, and elevates the expression of osteogenic markers ALP and OCN

Under development

Apt

Apt01

Apt02

Material

VEGF receptor

They exhibit high affinity for VEGFR-1 and VEGFR-2

Simulating the function of VEGF-A, it has the potential to activate VEGR receptors and promote angiogenesis

Under development

Aptamer-agomiR-195

Drug

Endothelial cell

It specifically targets endothelial cells and increases miR-195 levels in cells

Increasing the number of CD31hiEmcnhi vessels in aged murines stimulates bone formation and improves bone strength

Under development

aptamer-antagomiR-188

Drug

BMSC

It regulates the expression of miR-188 in BMSCs

Reduce miR-188 levels in BMSCs to increase trabecular volume, quantity, and cortical bone thickness; decrease trabecular separation and intimal circumference; enhance bone strength; elevate the bone formation rate; reduce the number and area of adipocytes in the bone marrow; and increase the number and surface area of osteoblasts on the trabecular and intimal bone surfaces, thereby preventing bone loss and fat accumulation in the bone marrow of elderly murines

Under development

OS-7.9

Material

MG-63

It shows high affinity and specific binding to MG-63 cells, as well as recognition of lung and colon colorectal adenocarcinoma cell lines

It enables early diagnosis and targeted treatment of osteosarcoma and metastatic disease

Under development

317

SL1067

Material

IL-1α

It demonstrates high affinity and specific recognition of IL-1α

Inhibit the IL-1α signaling pathway to treat related inflammatory reactions and diseases

Under development

272

VR11

Material

TNFα

It exhibits high affinity binding and specific recognition of TNFα, inhibiting its receptor binding and blocking TNFα-induced cytotoxicity and NO production

Treat inflammatory diseases and avoid immune reactions

Under development

273

8A-35

Drug

IL-8

It shows high affinity binding to IL-8, inhibiting IL-8 receptor binding, regulating the IL-8-induced intracellular signaling pathway, and inhibiting neutrophil migration

Potential anti-cancer effects in treating inflammatory diseases

Under development

Apc001PE

aptscl56

Drug

The loop3 region of sclerostin

It inhibits the antagonistic effect of sclerostin on Wnt signaling pathway and osteogenic potential

It promotes bone formation without increasing cardiovascular risk

Under development
