We demonstrate, for the first time, how parylene-HT on SiO2 substrates can be used as a human cell patterning platform. We demonstrate this platform with hNT astrocytes, derived from the human NTera2.D1 cell line. We show how hNT astrocytes are attracted to Parylene-HT and repelled by the SiO2 and are shown to adopt a similar morphology as that attained on standard tissue culture polystyrene. Furthermore, parylene-HT was capable of patterning the astrocytes achieving a ratio of 8:1 for cells on parylene compared to SiO2. Thus, as parylene-HT has similar physical properties to parylene-C with the addition of UV and thermal resistance, parylene-HT represents a desirable alternative substrate for human cell patterning.

Comparative Analysis of 4NQO- and Ethanol-Induced Oral Epithelial Dysplasia and Oral Squamous Cell Carcinoma in Male and Female Mice: Association With Peripheral Blood Inflammatory Markers.
J Oral Pathol Med

Department of Oral and Maxillofacial Pathology, Federal University of Uberlândia, Uberlândia, Minas Gerais, Brazil.
Background: Considering that peripheral blood biomarkers are prognostic predictors for several human tumors, this study aimed to comparatively analyze the association of hematological alterations with the incidence of epithelial dysplasia (ED) and oral squamous cell carcinoma (OSCC) in male and female mice treated with 4-nitroquinoline-N-oxide (4NQO) and ethanol (EtOH).
Methods: 120 C57Bl/6J mice (60 males and 60 females) were allocated to four groups (n = 15). They were treated firstly either with 5 mg/mL propylene glycol (PPG) or 100 μg/mL 4NQO in the drinking water for 10 weeks, followed by sterilized water (HO) or 8% EtOH (v/v) for 15 weeks, as follows: PPG/HO, PPG/EtOH, 4NQO/HO, and 4NQO/EtOH (CEUA-UFU, #020/21).
Enhancing Bioactivity of Titanium-Based Materials Through Chitosan Based Coating and Calcitriol Functionalization.

Titanium (Ti)-based materials are favored for hard tissue applications, yet their bioinertness limits their success. This study hypothesizes that functionalizing Ti materials with chitosan nano/microspheres and calcitriol (VD) will enhance their bioactivity by improving cellular activities and mineralization. To test this, chitosan particles were applied uniformly onto Ti surfaces using electrophoretic deposition (EPD) at 20 V for 3 minutes.

Chronic Graft-versus-host disease (GVHD) is a major complication of allogeneic hematopoietic stem cell transplantation (HSCT), affecting the female genital tract in 25-66% of the patients. This condition, referred to as Genital GVHD is an underdiagnosed gynecologic comorbidity, that can significantly impair quality of life. We aimed to describe the prevalence and management of genital GVHD following HSCT.

A key challenge of the modern genomics era is developing empirical data-driven representations of gene function. Here we present the first unbiased morphology-based genome-wide perturbation atlas in human cells, containing three genome-wide genotype-phenotype maps comprising CRISPR-Cas9-based knockouts of >20,000 genes in >30 million cells. Our optical pooled cell profiling platform (PERISCOPE) combines a destainable high-dimensional phenotyping panel (based on Cell Painting) with optical sequencing of molecular barcodes and a scalable open-source analysis pipeline to facilitate massively parallel screening of pooled perturbation libraries.

Renal fibrosis is widely recognized as the ultimate outcome of many chronic kidney diseases. The process of epithelial-mesenchymal transition (EMT) plays a critical role in the progression of fibrosis following renal injury. UHRF1, as a critical epigenetic regulator, may play an essential role in the pathogenesis and progression of renal fibrosis and EMT.
