Methods can be carried out for preparing a cartilage cell culture, and for preparing a cartilage cell-loaded implant. Protease-resistant fragments of type II collagen and/or type I collagen can be used for the in vitro detection of cartilage tissue and/or for the in vitro determination of the purity of cartilage tissue. A kit can be used for carrying out the methods."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Identity and purity of tissue biopsies","description":"A method for the in vitro detection of cartilage tissue and/or for the in vitro determination of the purity of cartilage tissue includes: a) treating a tissue sample with a protease and b) testing the","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10539574","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
