Tissue clearing combined with high-resolution confocal imaging is a cutting-edge approach for dissecting the three-dimensional (3D) architecture of tissues and deciphering cellular spatial interactions under physiological and pathological conditions. Deciphering the spatial interaction of leptin receptor-expressing (LepR) stromal cells with other compartments in the bone marrow is crucial for a deeper understanding of the stem cell niche and the skeletal tissue. In this study, we introduce an optimized protocol for the 3D analysis of skeletal tissues, enabling the visualization of hematopoietic and stromal cells, especially LepR stromal cells, within optically cleared bone hemisections.

Population-level estimates in timeframes for reaching cervical cancer (CC) elimination (ie, <4 cases per 100,000 women) in the United States may mask potential disparities in achieving elimination among sub-populations. We used three independent Cancer Intervention and Surveillance Modeling Network (CISNET) models to estimate differences in the time to CC elimination across seven strata of correlated screening and human papillomavirus vaccination uptake, based on national survey data. Compared to the average population, elimination was achieved ≥22 years earlier for the high-uptake strata and ≥27 years later for the most extreme low-uptake strata.
