Tumor take rates & growth have demonstrated advantages over SCID and NSG mice, consistently increasing study success while reducing animal numbers (i.e. VCaP prostate, H358 NSCLC & PDX models). Tumors grow ~10x larger enabling PDX establishment in a single passage, shortening timelines and providing more translational studies. Below are some examples of how SRG OncoRat can be used to complement, confirm or in some cases replace your SCID mice or NSG mouse xenograft

Improved engraftment enables oncology research

[/fusion_title][fusion_text]

In SCID mice many xenografts show low, non-existent or inconsistent engraftment efficiency. Engraftment efficiencies in 5-20% range are quite common; making it challenging or impossible to generate a cohort of animals with similar tumor sizes for an efficacy study. The OncoRat has demonstrated improved take rates and kinetics enabling effective in vivo studies using tumor models not previously feasible. See our review White Paper on a recent Clinical Cancer Research publication demonstrating engraftment & growth of difficult VCaP & MDVR VCaP prostate cell lines.

[/fusion_text][fusion_accordion divider_line=”” class=”” id=””][fusion_toggle title=”OncoRat enables a xenograft model for prostate carcinoma not previously feasible in mouse” open=”no”]

VCaP prostate cancer cells known to have poor engraftment rates and kinetics in immunodeficient mice (i.e. nude mice, SCID mice, NSG mice), thrived in the OncoRat. Preclinical studies with standard of care agents against the VCaP tumor performed as expected.

Rats! Disease Models & Mechanisms. 2009;2(5-6):206-210). The rat’s size is appropriate for multiple dosing, particularly by routes other than oral, and for collection of multiple blood samples, which enable investigators to assess efficacy, systemic toxicity and PK/PD profile in a single animal over longer time periods. Traditionally, efficacy studies would take place in mouse models with the corresponding safety studies being conducted in rat; the resulting data comparisons are less than ideal.[/fusion_text][/fusion_builder_column][/fusion_builder_row][/fusion_builder_container]
