Objective: To compare the osteogenic potential of two human induced pluripotent stem cell lines (RIV9 and RIV4) to human H9 embryonic stem cells.

Summary: The study demonstrates that different hPSC lines, including individual hiPSC clones, could have inherently different abilities to produce functional osteoblasts potentially based on the methylation marks placed on promotor regions important for lineage decisions

Objective: The mechanisms underlying reduced neurogenesis in Parkinson’s Disease (PD) are not well established. The authors tested the hypothesis that noradrenergic and dopaminergic depletion, as occurs in PD, impairs hippocampal neurogenesis.

Summary: Mechanisms of neurotransmitter-based regulation of cognition and hippocampal neurogenesis may well overlap under certain conditions but the present results do not suggest a simple relationship associated with the degeneration of the two most prominently affected transmitter systems in PD.

Usage: Rats received 1 mcg Anti-DBH-SAP icv.

Objective: To investigate changes occurring in the heart, predominantly at pre- and early symptomatic ages, in the Taiwanese mouse model of severe Spinal muscular atrophy (SMA).

Summary: The findings support the requirement to develop systemic therapies for SMA capable of treating non-neuromuscular pathologies.

Objective: To determine if degeneration of BFCNs causes a decrease in neurotrophin levels in innervated brain areas, which in turn promotes the development of Amyloid beta  pathology and cognitive impairment.

Summary: Lesion of septo-hippocampal BFCNs in a pre-symptomatic transgenic amyloid AD mouse model (APP/PS1 mice) increases soluble Ab levels in the hippocampus, and induces cognitive deficits in a spatial memory task that are not seen in either unlesioned APP/PS1 or non-transgenic littermate control mice. Cognitive decline and Amyloid-beta pathology induced by cholinergic basal forebrain neuron loss occur independent of dysfunctional neuronal BDNF signaling, and may therefore be directly underpinned by reduced cholinergic neurotransmission.

Usage: To lesion BFCNs, a single infusion of murine p75-SAP or control rabbit IgG-SAP (0.4 mg/ml) was stereotaxically injected into the basal forebrain.

Biomed Mater 13:034101. doi: 10.1088/1748-605X/aa95f8 PMID: 29068322

Objective: To improve grafted cell survival in the injured spinal cord, which is typically low.

Summary: It is of utmost importance to define the precise culture/transplantation parameters for maintenance of normal cell function and safe and effective use of cell therapy.

Summary: The effectiveness of the studies of the pathogenesis of AD and search for the strategies of its prevention and treatment depend on appropriate modeling of the pathological conditions in the brain leading to AD. Traditionally, the main focus on designing animal models of AD was related to the identification of brain areas and mediator systems related to memory. One model employed injections of a monoclonal antibody against growth factor receptor conjugated with saporin (192 IgG-saporin), which also resulted in the loss of cholinergic neurons and cognitive disorder

CNS Neurol Disord Drug Targets 17:106-112. doi: 10.2174/1871527317666180314115623

Objective: To establish the relationship between the depletion of orexin neurons and the number of proliferating cells in the subventricular zone.

Summary: The adult subventricular zone is affected by orexinergic signaling, the functional implication of which must be further elucidated.

Usage: 90 ng of Orexin-SAP or pyrogen-free saline was stereotaxically injected into the lateral hypothalamus (3.2 caudal, 1.7 lateral to bregma, 8.1 ventral to the skull surface) of male Wistar rats.

Objective: To investigate whether the proinflammatory cytokine MIF participates in the regulation of neuropathic hypersensitivity by interacting with and suppressing the descending dopaminergic system.

Summary: MIF functions as a braking factor in curbing dopaminergic descending inhibition in peripheral nerve injury-induced hypersensitivity by mediating Th gene methylation through G9a/SUV39H1-associated H3K9 methylation.

Usage: Anti-DAT-SAP was injected i.t. or i.c.v. with ISO-1 alone or ISO-1 combined with one of the other regulators on Day 7 post-nerve injury for 14 days, and pain behaviors, including 50% withdrawal threshold, mechanical pressure and thermal withdrawal latency, were observed throughout the 70 days post nerve injury.
