Teratoma Formation Analysis

Service to confirm pluripotency of human and mouse ESC and iPSC lines by Teratoma Formation Analysis after injection of cells into an animal.

Features:

• Turnaround time: 4 weeks (Mouse), 7 weeks (Human)
• Number of cells required / injection site: Mouse ESCs/iPSCs = 0.5 x 10^6,  Human ESCs/iPSCs =  1 x 10^6
• Enhanced experimental protocol: Injection under both the kidney capsule and in testis results in higher efficiency of distinct teratoma formations with differentiated tissues derived from all three germ layers.

Service Includes:

• Comprehensive report with histological analysis and high resolution publication-grade images of endoderm, mesoderm and ectoderm formation.
• Tissue blocks and H&E stained tissue section slides

Notes:

• Frozen sample culture Fee $895 per line (No fee for fresh cells)
• Pathogen tests (please provide mycoplasma test result showing negative; otherwise additional testing fee will be required.) 
• Kidney capsule tumor and testis tumor from each mouse will be embedded in one block. Separate blocks are available upon request with additional fee.
• Frozen tissue blocks are available with additional fee.

Technical Details:

• Experimental setup: A total of 4 mice (3 experimental and 1 control) will be used.
• Injection site: Each recipient mouse will be injected at two locations: in the kidney capsule and in the testis.
• Service includes: Cell injection, teratoma harvesting, tissue preparation (embedding and sectioning), H&E staining and histology analysis of teratoma tissue sections.
