Cellular basis of differential endochondral growth in Lake Malawi cichlids
Developmental Dynamics, Volume 251, Issue 12, Page 2001-2014, December 2022., 2022 Abstract Background The shape and size of skeletal elements is determined by embryonic patterning mechanisms as well as localized growth and remodeling during post‐embryonic development. Differential growth between endochondral growth plates underlies many aspects of morphological diversity in tetrapods but has not been investigated in ray‐finned ...

Feature-Driven 3D Building Modeling using Planar Halfspaces [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2013 With the exception of pure data-driven methods, reconstruction approaches for 3D building models from aerial point clouds often incorporate some level of model information to construct regularized and well-formed roof structures.

Advanced Science, EarlyView.Sperm‐derived circRNA‐1572 competitively binds to bta‐miR‐2478‐L‐2 through a “sponge” mechanism to regulate cyclin B2 (CCNB2) expression, thereby modulating the distribution of fibrous actin (F‐actin) in early pig embryos, ensuring proper chromosome segregation during mitosis, and facilitating normal embryo cleavage and zygotic genome activation.

Quantifying Genomic Imprinting at Tissue and Cell Resolution in the Brain
Epigenomes, 2020 Imprinted genes are a group of ~150 genes that are preferentially expressed from one parental allele owing to epigenetic marks asymmetrically distributed on inherited maternal and paternal chromosomes. Altered imprinted gene expression causes human brain

Involvement of IGF-2, IGF-1R, IGF-2R and PTEN in development of human tooth germ – an immunohistochemical study [PDF]
Organogenesis, 2016 Insulin-Like Growth Factor 2 (IGF-2) is a peptide hormone essential for prenatal growth and development. IGF-2 exerts its mitogenic effects via Insulin-Like Growth Factor 1 Receptor (IGF-1R), and is eliminated by binding to Insulin-Like Growth Receptor 2 (IGF-2R).

Advanced Science, EarlyView.The impact of topography on the secretome of adipose‐derived stem cells (ADSCs) has the potential for promoting tendon regeneration. The secretome generated from ADSCs on aligned structure has a potent effect in promoting cell migration, proliferation, tenogenic differentiation, macrophage M2 polarization, and tendon mechanical function recovery ...

The mGlu7 receptor provides protective effects against epileptogenesis and epileptic seizures
Neurobiology of Disease, 2019 Finding new targets to control or reduce seizure activity is essential to improve the management of epileptic patients. We hypothesized that activation of the pre-synaptic and inhibitory metabotropic glutamate receptor type 7 (mGlu7) reduces spontaneous ...

Functional and molecular heterogeneity of D2R neurons along dorsal ventral axis in the striatum
Nature Communications, 2020 Striatal dopaminoceptive neurons are molecularly and functionally heterogeneous. Here, the authors provide the translatome of D2R striatal neurons and identified hundreds of region specific molecular markers as well as testing their resource to shed ...

IGF-I stimulation of luteinizing hormone secretion, IGF-binding proteins (IGFBPs) and expression of mRNAs for IGFs, IGF receptors and IGFBPs in the ovine pituitary gland [PDF]
Journal of Endocrinology, 2000 Circulating concentrations of insulin-like growth factor-I (IGF-I) are reduced in juvenile sheep during nutritional growth restriction and the associated delay in puberty. Since exogenous IGF-I has been shown to stimulate luteinizing hormone (LH) secretion, it is postulated that endogenous IGF-I may act as a stimulatory metabolic signal to the pubertal

Reinforcing Stromal Cell Spheroid Through Red‐Light Preconditioning for Advanced Vascularization
Advanced Science, EarlyView.This study presents a novel approach to enhance stromal cell therapy for myocardial infarction by combining OLED‐based photobiomodulation (OPBM) preconditioning with 3D spheroid culture of hADSCs. The engineered spheroids improve angiogenesis, arterialization, and cardiac function in vivo, offering a next‐generation therapeutic strategy to overcome ...
