Abstract:
BACKGROUND: Vitrified cryopreservation is a novel method for specimen preservation, which has a potential application value in the establishment of tumor biopsy biobank. OBJECTIVE: To investigate the effectiveness of vitrified cryopreservation and the feasibility in the establishment of tumor biopsy biobank. METHODS: The fresh biopsy specimens of liver metastasis from rectal cancer were randomized into vitrified cryopreservation and control groups. Then, the biopsy specimens from each group were implanted subcutaneously into the mouse back to establish the humanized mouse xenograft model. The biological characteristics and histological changes of tumor tissues in each group were detected by Calcein-AM/Hoechst33342 staining, as well as immunohistochemistry and hematoxylin-eosin staining. Totally 105 biopsy tissues of liver metastasis from rectal cancer were preliminarily collected and cryopreserved to establish the tumor biopsy biobank. RESULTS AND CONCLUSION: No significant differences in biological viability or histological features of tumor biopsy was detected before and after cryopreservation (P > 0.05), suggesting that vitrified cryopreservation can effectively preserve tumor biopsy and is favorable for the establishment of tumor biopsy biobank.
