Article Abstract
An assay was developed for determining cell division orientation on gradients. The methodology is based on permeating microfluidic devices with alkanethiols and subsequent printing of cell adhesive peptide gradient self-assembled monolayers (SAMs) for examining oriented cell divisions. To our knowledge, there has been no study examining the correlation between cell division orientations based on an underlying ligand gradient. These results implicate an important role for how the extracellular matrix may control cell division. These surfaces would allow for a range of cell behavior (polarization, migration, division, differentiation) studies on tailored biospecific gradients and as a potential biotechnological platform to assess small molecule perturbations of cell function.

Refractory cytomegalovirus (CMV) infection is a severe complication following umbilical cord blood transplantation (UCBT). Antiviral agents, the standard first-line therapy, are limited by toxicity and resistance without robust T-cell immunity. We evaluated third-party donor (TPD)-derived CMV-specific T cells (CMVSTs) as a treatment option.

Background: PPM1D (protein phosphatase Mg⁺/Mn⁺ dependent 1D) is a Ser/Thr phosphatase that negatively regulates p53 and functions as an oncogenic driver. Its gene amplification and overexpression are frequently observed in various malignancies and disruption of PPM1D degradation has also been reported as a cause of cancer progression. However, the precise mechanisms regulating PPM1D stability remain to be elucidated.

Endothelial Colony-Forming Cells (ECFCs) are recognized as key vasculogenic progenitors in humans and serve as valuable liquid biopsies for diagnosing and studying vascular disorders. In a groundbreaking study, Anceschi et al. present a novel, integrative strategy that combines ECFCs loaded with gold nanorods (AuNRs) to enhance tumor radiosensitization through localized hyperthermia.

Primary gastric squamous cell carcinoma (GSCC) or gastric adenosquamous carcinoma (GASC) is an uncommon histologic type for which no standard treatment has been established. The prognosis is poor, and there are few reports of effective treatment. Here, we experienced a case of GASC that was diagnosed preoperatively as GSCC and could be operated on after successful preoperative chemotherapy with pembrolizumab, 5-fluorouracil, and cisplatin.

Plasmablastic lymphoma (PBL) is a rare and aggressive non-Hodgkin lymphoma with a poor prognosis and short survival rates. It is classified as a large B-cell lymphoma subtype, but carries a plasmacytic immunophenotype. Therefore, PBL has pathogenetic overlaps with diffuse large B-cell lymphoma not otherwise specified (DLBCL NOS) and plasma cell neoplasms (PCNs).
