Abstract
This study describes charges, outcomes, and recidivism in both the juvenile and adult criminal justice systems (CJS) for young adults aged 17 to 23 years with autism spectrum disorder (ASD; n = 606). Results are compared to individuals with ID (n = 1271) and a population control group (n = 2973). About 3% of individuals with ASD were charged with at least one offense by the time they reached young adulthood. Few differences were found in CJS involvement across groups. Young adults with ASD were not over represented in the CJS in general, and were less likely to be involved in the adult justice system than their peers. They received similar charges and outcomes and were as likely to reoffend as their peers.

Abstract
The regeneration of injured spinal cord is hampered by the lack of vascular supply and neurotrophic support. Transplanting tissue-engineered constructs with developed vascular networks and neurotrophic factors, and further understanding the pattern of vessel growth in the remodeled spinal cord tissue are greatly desired. To this end, highly vascularized scaffolds embedded with human dental pulp stem cells (DPSCs) are fabricated, which possess paracrine-mediated angiogenic and neuroregenerative potentials. The potent pro-angiogenic effect of the prevascularized scaffolds is first demonstrated in a rat femoral bundle model, showing robust vessel growth and blood perfusion induced within these scaffolds postimplantation, as evidenced by laser speckle contrast imaging and 3D microCT dual imaging modalities. More importantly, in a rat complete spinal cord transection model, the implantation of these scaffolds to the injured spinal cords can also promote revascularization, as well as axon regeneration, myelin deposition, and sensory recovery. Furthermore, 3D microCT imaging and novel morphometric analysis on the remodeled spinal cord tissue demonstrate substantial regenerated vessels, more significantly in the sensory tract regions, which correlates with behavioral recovery following prevascularization treatment. Taken together, prevascularized DPSC-embedded constructs bear angiogenic and neurotrophic potentials, capable of augmenting and modulating SCI repair.

The role of endothelial HIF-1 αin the response to sublethal hypoxia in C57BL/6 mouse pups. J Transl Med 2017; 97:356-369.

Abstract
Chronic sublethal hypoxia, a complication of premature birth, is associated with cognitive and motor handicaps. Responsiveness to and recovery from this hypoxic environment is dependent on induction of HIF-1 α in the cells affected. Microvascular endothelial-glial and microvascular endothelial-neuronal precursor interactions have been found to be dynamic and reciprocal, involving autocrine and paracrine signaling, with response and recovery correlated with baseline levels and levels of induction of HIF-1 α.To ascertain the roles of endothelial HIF-1 α in the responses of brain microvascular endothelial cells (EC) and neuronal precursors to hypoxia, we examined the effects of the presence and absence of endothelial HIF-1 α expression in culture and in cells comprising the subventricular zone (SVZ) and dentate gyrus under normoxic and hypoxic conditions. We used C57BL/6 WT and EC HIF-1 α -deficient mice and brain microvascular ECs isolated from these mice in western blots, immunofluorescence, and behavioral studies to examine the roles of EC HIF-1 α behaviors of endothelial and neuronal precursor cells (NPCs) in SVZ and hippocampal tissues under normoxic and hypoxic conditions and behaviors of these mice in open field activity tests. Analyses of ECs and SVZ and dentate gyrus tissues revealed effects of the absence of endothelial HIF-1 α on proliferation and apoptosis as well as open field activity, with both ECs and neuronal cells exhibiting decreased proliferation, increased apoptosis, and pups exhibiting gender-specific differences in open field activities. Our studies demonstrate the autocrine and paracrine effects of EC HIF-1 α-modulating proliferative and apoptotic behaviors of EC and NPC in neurogenic regions of the brain and gender-specific behaviors in normoxic and hypoxic settings.

A hydrogel-endothelial cell implant mimics infantile hemangioma: modulation by survivin and the Hippo pathway. J Transl Med 2015; 95:765-80. [PMID: 25961170 PMCID: PMC4828971 DOI: 10.1038/labinvest.2015.61] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2014] [Revised: 03/04/2015] [Accepted: 03/16/2015] [Indexed: 12/16/2022] Open
Abstract
Microvascular endothelial cells cultured in three-dimensional hydrogel scaffolds form a network of microvessel structures when implanted subcutaneously in mice, inosculate with host vessels, and over time remodel into large ectatic vascular structures resembling hemangiomas. When compared with infantile hemangiomas, similarities were noted, including a temporal progression from a morphological appearance of a proliferative phase to the appearance of an involuted phase, mimicking the proliferative and involutional phases of infantile hemangioma. Consistent with the progression of a proliferative phase to an involuted phase, both the murine implants and human biopsy tissue exhibit reduced expression of Ajuba, YAP, and Survivin labeling as they progressed over time. Significant numbers of CD45+, CD11b+, Mac3+ mononuclear cells were found at the 2-week time point in our implant model that correlated with the presence of CD45+, CD68+ mononuclear cells observed in biopsies of human proliferative-phase hemangiomas. At the 4-week time point in our implant model, only small numbers of CD45+ cells were detected, which again correlated with our findings of significantly diminished CD45+, CD68+ mononuclear cells in human involutional-phase hemangiomas. The demonstration of mononuclear cell infiltration transiently in the proliferative phase of these lesions suggests that the vascular proliferation and/or regression may be driven in part by an immune response. Gross and microscopic morphological appearances of human proliferative and involutional hemangiomas and our implant model correlate well with each other as do the expression levels of Hippo pathway components (Ajuba and YAP) and Survivin and correlate with proliferation in these entities. Inhibitors of Survivin and Ajuba (which we have demonstrated to inhibit proliferation and increase apoptosis in murine hemangioendothelioma cell tissue culture) may have potential as other beneficial treatments for proliferating infantile hemangiomas. This implant model may have potential as a modest through-put screen for testing and development of therapeutics targeted at the proliferative phase of infantile hemangiomas, reducing the subsequent postinvolutional scarring or deformities sometimes associated with these lesions.

Abstract
Brain and vascular cells form a functionally integrated signalling network that is known as the neurovascular unit (NVU). The signalling (autocrine, paracrine and juxtacrine) between different elements of this unit, especially in humans, is difficult to disentangle in vivo. Developing representative in vitro models is therefore essential to better understand the cellular interactions that govern the neurovascular environment. We here describe a novel approach to assay these cellular interactions by combining a human adult cerebral microvascular endothelial cell line (hCMEC/D3) with a fetal ganglionic eminence-derived neural stem cell (hNSC) line. These cell lines provide abundant homogeneous populations of cells to produce a consistently reproducible in vitro model of endothelial morphogenesis and the ensuing NVU. Vasculature-like structures (VLS) interspersed with patches of differentiating neural cells only occurred when hNSCs were seeded onto a differentiated endothelium. These VLS emerged within 3 days of coculture and by day 6 were stabilizing. After 7 days of coculture, neuronal differentiation of hNSCs was increased 3-fold, but had no significant effect on astrocyte or oligodendrocyte differentiation. ZO1, a marker of adherens and tight junctions, was highly expressed in both undifferentiated and differentiated endothelial cells, but the adherens junction markers CD31 and VE-cadherin were significantly reduced in coculture by approximately 20%. A basement membrane, consisting of laminin, vitronectin, and collagen I and IV, separated the VLS from neural patches. This simple assay can assist in elucidating the cellular and molecular signaling involved in the formation of VLS, as well as the enhancement of neuronal differentiation through endothelial signaling.

Abstract
Premature infants often experience chronic hypoxia, resulting in cognitive & motor neurodevelopmental handicaps. These sometimes devastating handicaps are thought to be caused by compromised neural precursor cell (NPC) repair/recovery resulting in variable central nervous system (CNS) repair/recovery. We have identified differential responses of two mouse strains (C57BL/6 & CD1) to chronic hypoxia that span the range of responsiveness noted in the premature human population. We previously correlated several CNS tissue and cellular behaviors with the different behavioral parameters manifested by these two strains. In this report, we use unbiased array technology to interrogate the transcriptome of the subventricular zone (SVZ) in these strains. Our results illustrate differences in mRNA expression in the SVZ of both C57BL/6 and CD1 mice following hypoxia as well as differences between C57BL/6 and CD1 SVZ under both normoxic and hypoxic conditions. Differences in expression were found in gene sets associated with Sox10-mediated neural functions that explain, in part, the differential cognitive and motor responsiveness to hypoxic insult. This may shed additional light on our understanding of the variable responses noted in the human premature infant population and facilitate early intervention approaches. Further interrogation of the differentially expressed gene sets will provide a more complete understanding of the differential responses to, and recovery from, hypoxic insult allowing for more informed modeling of the ranges of disease severity observed in the very premature human population.
