Abstract
The vertebrate enteric nervous system (ENS) is a crucial network of enteric neurons and glia resident within the entire gastrointestinal tract (GI). Overseeing essential GI functions such as gut motility and water balance, the ENS serves as a pivotal bidirectional link in the gut-brain axis. During early development, the ENS is primarily derived from enteric neural crest cells (ENCCs). Disruptions to ENCC development, as seen in conditions like Hirschsprung disease (HSCR), lead to the absence of ENS in the GI, particularly in the colon. In this study, using zebrafish, we devised an in vivo F0 CRISPR-based screen employing a robust, rapid pipeline integrating single-cell RNA sequencing, CRISPR reverse genetics, and high-content imaging. Our findings unveil various genes, including those encoding opioid receptors, as possible regulators of ENS establishment. In addition, we present evidence that suggests opioid receptor involvement in the neurochemical coding of the larval ENS. In summary, our work presents a novel, efficient CRISPR screen targeting ENS development, facilitating the discovery of previously unknown genes, and increasing knowledge of nervous system construction.

Abstract
Opioids are considered the oldest drugs known by humans and have been used for sedation and pain relief for several centuries. Nowadays, endogenous opioid peptides are divided into four families: enkephalins, dynorphins, endorphins, and nociceptin/orphanin FQ. They exert their action through the opioid receptors (ORs), transmembrane proteins belonging to the super-family of G-protein-coupled receptors, and are expressed throughout the body; the receptors are the δ opioid receptor (DOR), μ opioid receptor (MOR), κ opioid receptor (KOR), and nociceptin/orphanin FQ receptor (NOP). Endogenous opioids are mainly studied in the central nervous system (CNS), but their role has been investigated in other organs, both in physiological and in pathological conditions. Here, we revise their role in stem cell (SC) biology, since these cells are a subject of great scientific interest due to their peculiar features and their involvement in cell-based therapies in regenerative medicine. In particular, we focus on endogenous opioids' ability to modulate SC proliferation, stress response (to oxidative stress, starvation, or damage following ischemia-reperfusion), and differentiation towards different lineages, such as neurogenesis, vasculogenesis, and cardiogenesis.

Abstract
Axonal regeneration and formation of tripartite (axo-glial) junctions at damaged sites is a prerequisite for early repair of injured spinal cord. Transplantation of stem cells at such sites of damage which can generate both neuronal and glial population has gained impact in terms of recuperation upon infliction with spinal cord injury. In spite of the fact that a copious number of pre-clinical studies using different stem/progenitor cells have shown promising results at acute and subacute stages, at the chronic stages of injury their recovery rates have shown a drastic decline. Therefore, developing novel therapeutic strategies are the need of the hour in order to assuage secondary morbidity and effectuate improvement of the spinal cord injury (SCI)-afflicted patients' quality of life. The present review aims at providing an overview of the current treatment strategies and also gives an insight into the potential cell-based therapies for the treatment of SCI.

Abstract
Dissolution of atmospheric plasma sprayed (APS) hydroxyapatite (HAp) coatings on Ti-6Al-4 V medical implants have always been a challenge to overcome in the field of biomedical industry. In the present work, an attempt has been made to develop a HAp coating using a novel thermal spray process called axial suspension plasma spraying (SPS), which leads to thin adherent coatings. Two HAp coatings fabricated by APS (P1 and P2) and four SPS HAp coatings (S1, S2, S3 and S4) produced with varying spraying parameters were characterized in terms of (1) microstructure, porosity, hardness, adhesion strength, contact angle and phase purity; (2) corrosion resistance in 10% Fetal bovine serum (FBS); (3) in-vitro cell adherence and cell viability using human umbilical cord blood-derived mesenchymal stem cells (hMSCs). Amongst different APS and SPS coatings, P1 and S3 exhibited superior properties. S3 coating developed using SPS exhibited 1.3 times higher adhesion strength when compared to APS coating (P1) and 9.5 times higher corrosion resistance than P1. In addition, both S3 and P1 exhibited comparatively higher biocompatibility as evidenced by the presence of more than 92% viable hMSCs.

Abstract
The pathophysiology of Parkinson's disease exhibit imperative roles in unfolded protein response stress-induced oxidative stress and inflammation in general. Although, delta opioid receptor (DOR), has been found to represent anti-parkinsonian effect at behavioral level, its underlying mechanism remains elusive till date. In the present study the role of DOR agonist, SNC-80 and the consorted molecular mechanisms, which translates to behavioral recuperation, has been delineated. In order to mimic PD, mice were intra-peritoneally injected with MPTP, following exposure to SNC-80 and L-DOPA to elucidate amelioration of the MPTP-induced behavioral impairments. The results obtained suggest that the severity of the compromised motor functions up-regulated the UPR stress sensors: IRE-1α/Bip/CHOP, oxidative stress along with the pro-inflammatory cytokines: IL1β/IFNγ/TNFα and IL-6. These inimical factors combined, aids the persistence of the disease in MPTP intoxicated mice. Supplementation with SNC-80 significantly improved motor functions via down-regulation of the UPR stress sensors and inflammatory cytokines. Additionally, SNC-80 could upregulate Nrf-2 and Heme oxygenase-1 (HO-1) protein expression indicating their involvement in SNC-80's potential anti-oxidant function. There was also a significant reduction in protein carbonyl content indicating the positive role of SNC-80 in dampening MPTP induced oxidative stress. Concomitantly, L-DOPA also demonstrated an enhanced effect towards improvement of motor functions but did not suppress the UPR and inflammatory responses caused due to MPTP intoxication. Hence, these results suggest that SNC-80 could hold a pivotal role in replenishing motor functions essentially via regulating UPR and inflammation.
