What is osteosarcoma?
Osteosarcoma is a type of bone cancer that primarily affects adolescents and young adults.
Why is RNA preservation important?
High-quality RNA is crucial for accurate gene expression analysis and understanding biological processes.
What challenges exist in spatial transcriptomic analysis?
Preserving RNA quality while maintaining tissue morphology is a significant challenge in spatial transcriptomics.
How does the new method improve RNA quality?
The method allows for effective decalcification of bone tissues, which helps preserve RNA integrity.
What are potential therapeutic targets identified in the study?
Several key genes associated with lung metastasis were identified as potential therapeutic targets.
Can this method be applied to other tissues?
