Genetics of gonadal stem cell renewal

LJ Greenspan, M De Cuevas… - Annual review of cell and …, 2015 - annualreviews.org
Stem cells are necessary for the maintenance of many adult tissues. Signals within the stem
cell microenvironment, or niche, regulate the self-renewal and differentiation capability of …

Activation of the EGFR/MAPK pathway drives transdifferentiation of quiescent niche cells to stem cells in the Drosophila testis niche

LJ Greenspan, M de Cuevas, KH Le, JM Viveiros… - Elife, 2022 - elifesciences.org
Adult stem cells are maintained in niches, specialized microenvironments that regulate their
self-renewal and differentiation. In the adult Drosophila testis stem cell niche, somatic hub …

[HTML][HTML] Coordinate Regulation of Stem Cell Competition by Slit-Robo and JAK-STAT Signaling in the Drosophila Testis

RR Stine, LJ Greenspan, KV Ramachandran… - PLoS …, 2014 - journals.plos.org
Stem cells in tissues reside in and receive signals from local microenvironments called niches.
Understanding how multiple signals within niches integrate to control stem cell function is …

To be or not to be: endothelial cell plasticity in development, repair, and disease

LJ Greenspan, BM Weinstein - Angiogenesis, 2021 - Springer
Endothelial cells display an extraordinary plasticity both during development and throughout
adult life. During early development, endothelial cells assume arterial, venous, or lymphatic …

[PDF][PDF] Retinoblastoma intrinsically regulates niche cell quiescence, identity, and niche number in the adult Drosophila testis

LJ Greenspan, EL Matunis - Cell reports, 2018 - cell.com
Homeostasis in adult tissues depends on the precise regulation of stem cells and their
surrounding microenvironments, or niches. Here, we show that the cell cycle inhibitor and tumor …

R Olson, JA Hess, D Turk, M Marino, L Greenspan… - Trials, 2023 - Springer
Background Chronic pain is a prevalent and costly problem that often has occupational origins.
Home care workers (HCWs) are at high risk for work-related injuries, pain, and disability. …

Live Imaging of the Drosophila Testis Stem Cell Niche

LJ Greenspan, EL Matunis - Germline Stem Cells, 2017 - Springer
Live imaging of adult tissue stem cell niches provides key insights into the dynamic behavior
of stem cells, their differentiating progeny, and their neighboring support cells, but few …

The impact of COVID-19 on transit workers: perceptions of employer responses and associations with health factors

SPM Rice, LS Greenspan, TN Bauer… - Annals of Work …, 2022 - academic.oup.com
COVID-19 has had a substantial impact on transit workers’ lives, especially among public-facing
vehicle operators. The current project examined relationships between workers’ …

[HTML][HTML] Associations between variation in X chromosome male reproductive genes and sperm competitive ability in Drosophila melanogaster

L Greenspan, AG Clark - International journal of evolutionary biology, 2011 - hindawi.com
Variation in reproductive success has long been thought to be mediated in part by genes
encoding seminal proteins. Here we explore the effect on male reproductive phenotypes of X-…

Live Imaging of Cutaneous Wound Healing after Rotary Tool Injury in Zebrafish

LJ Greenspan, KK Ameyaw, D Castranova… - Journal of Investigative …, 2024 - Elsevier
Cutaneous wounds are common afflictions that follow a stereotypical healing process involving
hemostasis, inflammation, proliferation, and remodeling phases. In the elderly and those …
