What to know about Scientific Innovation

Researchers at Vanderbilt University, led by Professor Ken Lau, have developed a new method to recover whole cells from formalin-fixed, paraffin-embedded (FFPE) tissue samples. This technique improves the quality of single-cell RNA sequencing data compared to previous methods that only isolated nuclei, potentially unlocking valuable molecular data from archived patient samples.

What happened

Unlocking the past: New method helps gain insights into old tissues Gaby Clark Scientific Editor Alexander Pol Deputy Editor A book sits atop a table.

Why it matters

Although it's closed, its title, "Encyclopedia of Human Tissue," promises untold secrets.

Common ground

Perhaps with this book, you can learn about different cell types and what they look like under normal conditions or conditions of disease.

Claim 1: “Lau and colleagues, in a paper led by Evans and co-first author Joey Simmons... have built on a method that Simmons created to isolate and recover more high-quality, intact cells for further study.”
SINGLE SOURCE
While one source ('Unlocking the past') mentions a whole-cell isolation method for FFPE tissues, the specific names (Ken Lau, James Evans, Joey Simmons) are not corroborated by the other provided search results, which are unrelated (e.g., Ken the doll, Atlanta Braves).
