Highly precise micromanipulation tools that can manipulate and interrogate cell organelles and components must be developed to support the rapid development of new cell-based medical therapies, thereby facilitating in-depth understanding of cell dynamics, cell component functions, and disease mechanisms. This paper presents a literature review on micro/nanomanipulation tools and their control methods for single-cell surgery. Micromanipulation methods specifically based on laser, microneedle, and untethered micro/nanotools are presented in detail. The limitations of these techniques are also discussed. The biological significance and clinical applications of single-cell surgery are also addressed in this paper.

Adipose-derived stem cells (ADSCs) have an important role in the modulation of burned tissue repair through the release of paracrine factors that stimulate the wound healing response. In this study, we tested the hypothesis that smoking status alters the profile of paracrine factors secreted from ADSCs isolated from damaged adipose tissue. Adipose tissue was collected from adult patients (N=8) with severe burn injuries (>20% total body surface area) at the index operation.

Utilizing single-cell transcriptome sequencing (scRNA-seq) technology, this study explores the viability of employing mesenchymal stem cells (MSCs) as a therapeutic approach for age-related hearing loss (ARHL). The research demonstrates MSCs' ability to differentiate into inner ear cell subpopulations, particularly hair cells, delivering Apelin via extracellular vesicles (EVs) to promote M2 macrophage polarization. In vitro experiments show reduced inflammation and preservation of hair cell health.

Breast cancer is the most common malignant tumor in the world, and its metastasis is the main cause of death in breast cancer patients. However, the differences between primary breast cancer tissue and lymphatic node, bone, and brain metastases at the single-cell level are not fully understood. We analyzed the microenvironment heterogeneity in samples of primary breast cancer (n = 4), breast cancer lymphatic node metastasis (n = 4), breast cancer brain metastasis (n = 3), and breast cancer bone metastasis (n = 2) using single-cell sequencing data from the GEO database.

Tissue-resident immune cells (TRICs) are a highly heterogeneous and plastic subpopulation of immune cells that reside in lymphoid or peripheral tissues without recirculation. These cells are endowed with notably distinct capabilities, setting them apart from their circulating leukocyte counterparts. Many studies demonstrate their complex roles in both health and disease, involving the regulation of homeostasis, protection, and destruction.

Azvudine and nirmatrelvir-ritonavir (Paxlovid) were widely used to treat patients with COVID-19 in China during the Omicron wave. However, the efficacy and safety of azvudine versus Paxlovid are poorly established. This study included 40,876 hospitalized patients with COVID-19 from eleven hospitals in Henan and Xinjiang Provinces, China.
