Lindstrom and Tracy Tran / McMahon Lab USC Stem Cell GerolamoAuricchio/EyeEm/Getty Images Forget wrinkle creams, Botox, and cosmetic surgery. They won't remove the wrinkles that really count—the wrinkles in the nuclear lamina, the inner surface of the nuclear membrane. As the nuclear lamina accumulates wrinkles, it creates openings for transcription factors, which can then find their way to heterochromatin, tightly packed DNA. This DNA, which should be turned off, gets turned on instead, tipping cells toward dysfunction. Such changes in gene expression occur in old liver cells, observed scientists at the University of Virginia. Reporting in Aging Cell, the scientists associated laminar wrinkles with increased Foxa2 binding, de-repression of PPAR- and LXR-dependent gene expression, and development of fatty liver. Laminar wrinkles could also occur in other cell types, suggested the scien- tists, who added that the wrinkles could be removed if the nuclear membrane's lamin losses could be reversed, pos- sibly by lamin-transporting viruses. Just don't expect to see viral treatments at a spa anytime soon. A team of researchers from University of Southern California (USC) have been studying how nephron-forming progenitor cells (NPCs) become mature cell types in the kidney. The team genetically labelled in vitro mouse kidney NPCs and observed them with time-lapse microscopy. The team then used single-cell RNA-seq to document how NPCs turn into intermediate cell types with specific gene activity, which identifies them as the precursors to particular mature cell types. The results of this study were published in Developmental Cell. The team was able to interpret which genes were activated when specific cell types formed in the nephron. The researchers learned that early-arriving NPCs differ- entiate and become the tubule, which controls the reabsorption of im- portant compounds back into the blood and carries urine away. Later arrivals develop into the glomerulus, which filters blood. "Timing is critical in determining the type of mature cell that each progenitor will become," said Nils O. Lindstrom, Ph.D., a principal author of the study and a research associate in stem cell biology and regenera- tive medicine at USC's Keck School of Medicine. To develop better ani- mal models for drug development, scientists need to understand how these precursor cells form organs under normal circumstances. In addi- tion, these insights could facilitate the future manufacturing of organs for transplant. Kidney Progenitor Cells: Now Arriving They're not fingerprints, but microbial signatures constituting the unique microbial makeup of each individual can similarly identify persons involved in burglaries and other crimes that occur in the home, a study suggests. A team of researchers collected samples from the nostrils and hands of residents, and various surfaces from their respective homes in Chicago, IL, and Fort Lauderdale, FL, before and after mock burglaries by nonresidents. The investigators identified unique bacterial assemblages for each in- dividual, and generated models to discern the accuracy of predicting a nonresident interacting with a given home. A total of 9,965 unique operational taxonomic units (uOTUs) were identified among 30 individuals. Nonresidents' uOTUs were mapped to residents' home, showing an interaction accuracy of more than 60%. Observing the change in uOTUs over time, researchers found that appearance/disap- pearance rates showed no significant dif- ference in the absence or presence of other individuals. "With further improvement in detection of stable markers, the human microbiome may serve as an additional tool for human profiling and crime scene investigations," said Jarrad Hampton-Marcell, a Ph.D. candi- date at University of Illinois at Chicago and microbial ecologist at Argonne National Laboratory. Hampton-Marcell presented the study findings at ASM Microbe, the annual meet- ing of the American Society for Microbiol- ogy, held June 7–11 in Atlanta, GA.
