Induced Cognitive Impairments Reversed by Grafts of Neural Precursors: A Longitudinal Study in a Macaque Model of Parkinson's Disease

Advanced Science, 2022
Parkinson's disease (PD) evolves over an extended and variable period in humans; years prior to the onset of classical motor symptoms, sleep and biological rhythm disorders develop, significantly impacting the quality‐of‐life of patients.

Corticospinal neuron subpopulation-specific developmental genes prospectively indicate mature segmentally specific axon projection targeting

Cell Reports, 2021
Summary: For precise motor control, distinct subpopulations of corticospinal neurons (CSN) must extend axons to distinct spinal segments, from proximal targets in the brainstem and cervical cord to distal targets in thoracic and lumbar spinal segments ...

Dopamine modulates the retinal clock through melanopsin-dependent regulation of cholinergic waves during development

BMC Biology, 2023
Background The mammalian retina contains an autonomous circadian clock that controls various aspects of retinal physiology and function, including dopamine (DA) release by amacrine cells. This neurotransmitter plays a critical role in retina development,

Inter-axonal molecular crosstalk via Lumican proteoglycan sculpts murine cervical corticospinal innervation by distinct subpopulations

Cell Reports, 2023
Summary: How CNS circuits sculpt their axonal arbors into spatially and functionally organized domains is not well understood. Segmental specificity of corticospinal connectivity is an exemplar for such regional specificity of many axon projections ...

Liver organoids in domestic animals: an expected promise for metabolic studies

Veterinary Research, 2021
The liver is one of the most important organs, both in terms of the different metabolic processes (energy, lipid, ferric, uric, etc.) and of its central role in the processes of detoxification of substances of food origin or noxious substances (alcohol ...

Anastasis in Glioblastoma, Brain Cancer Stem, and Brain Stem Cells

Journal of Basic and Clinical Health Sciences, 2021
Objective: Anastasis, a process that has been discovered recently, halts apoptosis, and thus, recovers the survival functions of cells. It may be suggested that anastasis is related to cancer progression, especially in cancer stem cells which are responsible for therapy resistance, metastasis, and recurrence.

Crim1 and Kelch-like 14 exert complementary dual-directional developmental control over segmentally specific corticospinal axon projection targeting

Cell Reports, 2021
Summary: The cerebral cortex executes highly skilled movement, necessitating that it connects accurately with specific brainstem and spinal motor circuitry.

Persistent Wnt/β-catenin signaling determines dorsalization of the postnatal subventricular zone and neural Stem cell specification into oligodendrocytes and glutamatergic neurons [PDF]

, 2014
In the postnatal and adult central nervous system (CNS), the subventricular zone (SVZ) of the forebrain is the main source of neural stem cells (NSCs) that generate olfactory neurons and oligodendrocytes (OLs), the myelinating cells of the CNS.

Epigenetic status of H19/IGF2 and SNRPN imprinted genes in aborted and successfully derived embryonic stem cell lines in non-human primates

Stem Cell Research, 2016
The imprinted genes of primate embryonic stem cells (ESCs) often show altered DNA methylation. It is unknown whether these alterations emerge while deriving the ESCs. Here we studied the methylation patterns of two differentially methylated regions (DMRs)
