Orthotopic Model

The xenogeneic orthotopic tumor transplantation model can allow studies that assess the interaction of tumor cells and the organ microenvironment between the surrounding stroma so that tumor growth can be monitored when evaluating drug efficacy.

Cancer Type	Orthotopic Model	Orthotopic Model (Luc Cell Line)
Brain Cancer	U87-MG	U87-MG-luc
Lung cancer	NCI-H1650, A549, NCI-H1975, NCI-H460, LLC1	A549-luc,LLC1-luc, NCI-H1975-luc
Colon cancer	HCT-116, LoVo	HT29-luc
Gastric cancer	Hs 746T
Pancreas cancer	Mia-Paca 2	Mia-Paca ;2-luc
Breast cancer	MDA-MB-231	4T1-luc
Ovarian cancer	SK-OV-3	SK-OV-3-luc
Prostate Cancer	PC3	PC-3-luc
Renal Cancer	A498
Bladder Cancer	UM-UC-3
Melanoma		B16-F10-luc
Liver Cancer	H22
Bone Cancer

At present, Medicilon has mature orthotopic transplantation technology, including orthotopic brain, orthotopic liver, orthotopic lung, orthotopic tibia marrow cavity and orthotopic intravesical transplantation.

PDX Models

The human tumor transplantation model PDX retains the characteristics of the patient’s tumor tissue and is more clinically relevant. Combined with humanized mice, it can establish an ideal tumor immunotherapy evaluation model.

Medicilon has now developed:

FAQs

What is Car-T Cell Therapy?

CAR-T immunotherapy (Chimeric Antigen Receptor T-cell Therapy) refers to the transfer of genetic material encoding specific antigen recognition domains and T cell activation signals into T cells through gene modification technology. This enables T cells to recognize and bind to specific antigens present on the surface of tumor cells, activating them to directly kill tumor cells by releasing perforins, granzyme B, etc. Additionally, CAR-T cells recruit endogenous immune cells by releasing cytokines, enhancing the immune system's ability to target and kill tumor cells. This approach aims to treat tumors effectively and can also establish memory T cells for sustained, specific anti-tumor effects.
