AI Article Synopsis

  • The study establishes long-term cultures of both murine and human salivary gland organoids that retain gland-specific genes and functions, helping to better understand salivary gland biology.
  • Human organoids can be derived from different cell types while maintaining their characteristics, indicating the ability to replicate the diversity of human salivary glands.
  • The research also enables the creation of tumoroid cultures for various types of salivary gland tumors, providing a platform for advancements in precision medicine and cancer treatment.

Article Abstract

Salivary glands that produce and secrete saliva, which is essential for lubrication, digestion, immunity, and oral homeostasis, consist of diverse cells. The long-term maintenance of diverse salivary gland cells in organoids remains problematic. Here, we establish long-term murine and human salivary gland organoid cultures. Murine and human salivary gland organoids express gland-specific genes and proteins of acinar, myoepithelial, and duct cells, and exhibit gland functions when stimulated with neurotransmitters. Furthermore, human salivary gland organoids are established from isolated basal or luminal cells, retaining their characteristics. Single-cell RNA sequencing also indicates that human salivary gland organoids contain heterogeneous cell types and replicate glandular diversity. Our protocol also enables the generation of tumoroid cultures from benign and malignant salivary gland tumor types, in which tumor-specific gene signatures are well-conserved. In this study, we provide an experimental platform for the exploration of precision medicine in the era of tissue regeneration and anticancer treatment.

Herbivore insects deploy salivary effectors to manipulate the defense of their host plants. However, it remains unclear whether small RNAs from insects function as effectors in regulating plant-insect interactions. Here, we report that a microRNA (miR29-b) found in the saliva of phloem-feeding whitefly (Bemisa tabaci) can transfer into the host plant phloem during feeding and fine-tune the defense response of tobacco (Nicotiana tabacum).

The tumor microenvironment characterized by heterogeneously organized vasculatures causes intra-tumoral heterogeneity of oxygen partial pressure at the cellular level, which cannot be measured by current imaging techniques. The intra-tumoral cellular heterogeneity may lead to a reduction of therapeutic effects of radiation. The purpose of this study was to investigate the effects of the heterogeneity on biological effectiveness of H-, He-, C-, O-, and Ne-ion beams for different oxygenation levels, prescribed dose levels, and cell types.

Background: The long-term effect of adipose-derived mesenchymal stromal cells (ASCs) to restore radiation-induced salivary gland hypofunction in previous head and neck cancer patients have not been validated in larger settings.

Methods: The study was the 12-months follow-up of a randomised trial, including patients with hyposalivation. Patients were randomised to receive allogeneic ASCs or placebo in the submandibular glands.

Introduction: Sialorrhea may be a consequence of severe acquired brain injury (ABI). Salivary gland botulinum neurotoxin (SG-BoNT) injections can reduce saliva production, but there is limited evidence for their use in ABI.We reviewed the effectiveness, impact on chest infection frequency, and safety of SG-BoNT for sialorrhea in a cohort of patients with severe ABI.
