Recently abstinent methamphetamine (Meth) abusers showed neurovascular dysregulation within the striatum. The factors that contribute to this dysregulation and the persistence of these effects are unclear. The current study addressed these knowledge gaps. First, we evaluated the brains of rats with a history of Meth self-administration following various(More)
Enhanced understanding of differential gene expression and biological pathways associated with distinct phases of intramembranous bone regeneration following femoral marrow ablation surgery will improve future advancements regarding osseointegration of joint replacement implants, biomaterials design, and bone tissue engineering. A rat femoral marrow(More)
The common premise of synthetic implants in the restoration of diseased tissues and organs is to use inert and solid materials. Here, a porous titanium implant was fabricated for the delivery of microencapsulated bioactive cues. Control-released transforming growth factor-beta1 (TGF-beta1) promoted the proliferation and migration of human mesenchymal stem(More)
Craniosynostosis occurs in one of 2500 live human births and may manifest as craniofacial disfiguration, seizure, and blindness. Craniotomy is performed to reshape skull bones and resect synostosed cranial sutures. We demonstrate for the first time that autologous mesenchymal stem cells (MSCs) and controlled-released TGFbeta3 reduced surgical trauma to(More)
The G171V mutation in the low-density lipoprotein receptor-related protein 5 (LRP5) leads to a high bone mass (HBM) phenotype. Studies using HBM transgenic mouse models have consistently found increased bone mass and whole-bone strength, but little attention has been paid to the composition of the bone matrix. The current study sought to determine if the(More)
Sclerostin and parathyroid hormones are strong negative and positive regulators of bone formation, respectively. The anabolic response induced by intermittent (iPTH) treatment is sclerostin status-dependent. However, the interaction between sclerostin and iPTH at the matrix level is unknown. The goal of the current study was to determine if iPTH treatment(More)
