2.Research advances on stem cell-based treatments in animal studies and clinical trials of lymphedema.
Chinese Journal of Reparative and Reconstructive Surgery 2024;38(1):99-106
OBJECTIVE:
To summarize the progress of the roles and mechanisms of various types of stem cell-based treatments and their combination therapies in both animal studies and clinical trials of lymphedema.
METHODS:
The literature on stem cell-based treatments for lymphedema in recent years at home and abroad was extensively reviewed, and the animal studies and clinical trials on different types of stem cells for lymphedema were summarized.
RESULTS:
Various types of stem cells have shown certain effects in animal studies and clinical trials on the treatment of lymphedema, mainly through local differentiation into lymphoid endothelial cells and paracrine cytokines with different functions. Current research focuses on two cell types, adipose derived stem cells and bone marrow mesenchymal stem cells, both of which have their own advantages and disadvantages, mainly reflected in the therapeutic effect of stem cells, the difficulty of obtaining stem cells and the content in vivo. In addition, stem cells can also play a synergistic role in combination with other treatments, such as conservative treatment, surgical intervention, cytokines, biological scaffolds, and so on. However, it is still limited to the basic research stage, and only a small number of studies have completed clinical trials.
CONCLUSION
Stem cells have great transformation potential in the treatment of lymphedema, but there is no unified standard in the selection of cell types, the amount of transplanted cells, and the timing of transplantation.

BACKGROUND:
Immunotherapies such as adoptive immune cell infusion and immune-modulating agents are widely used for cancer treatment, and the concomitant symptoms, including cytokine release syndrome (CRS) or immune-related adverse events (irAEs), are frequently reported. However, clinical manifestations induced by mismatched donor granulocyte colony-stimulating factor mobilized peripheral blood mononuclear cell (GPBMC) infusion in patients receiving microtransplant (MST) have not yet been well depicted.
METHODS:
We analyzed 88 cycles of mismatched GPBMC infusion in patients with acute myeloid leukemia receiving MST and 54 cycles of chemotherapy without GPBMC infusion as a comparison. Clinical symptoms and their correlation with clinical features, laboratory findings, and clinical response were explored.
RESULTS:
Fever (58.0% [51/88]) and chills (43.2% [38/88]) were the significant early-onset symptoms after GPBMC infusion. Patients possessing less human leukocyte antigen-matching loci with the donor or those with unrelated donors experienced more chills (3 [2-5] loci vs. 5 [3-5] loci, P = 0.043 and 66.7% [12/18] vs. 37.1% [26/70], P = 0.024). On the other hand, those with decreased CD4 + /CD8 + T-cell ratio developed more fever (0.8 [0.7-1.2] vs. 1.4 [1.1-2.2], P = 0.007). Multivariable analysis demonstrated that younger patients experienced more fever (odds ratio [OR] = 0.963, 95% confidence interval [CI]: 0.932-0.995, P = 0.022), while patients with younger donors experienced more chills (OR = 0.915, 95% CI: 0.859-0.975, P = 0.006). Elevated ultra-sensitive C-reactive protein levels in the absence of cytokine storm were observed following GPBMC infusion, which indicated mild and transient inflammatory response. Although no predictive value of infusion-related syndrome to leukemia burden change was found, the proportion of host pre-treatment activated T cells was positively correlated with leukemia control.
CONCLUSIONS
Mismatched GPBMC infusion in MST induced unique infusion-related symptoms and laboratory changes, which were associated with donor- or recipient-derived risk factors, with less safety and tolerance concerns than reported CRS or irAEs.

A triple-transgenic (tyrosine hydroxylase/dopamine decarboxylase/GTP cyclohydrolase 1, TH/DDC/GCH1) bone marrow mesenchymal stem cell line (BMSCs) capable of stably synthesizing dopamine (DA) transmitters were established to provide experimental evidence for the clinical treatment of Parkinson's disease (PD) by using this cell line. The DA-BMSCs cell line that could stably synthesize and secrete DA transmitters was established by using the triple transgenic recombinant lentivirus. The triple transgenes (TH/DDC/GCH1) expression in DA-BMSCs was detected using reverse transcription-polymerase chain reaction (RT-PCR), Western blotting, and immunofluorescence. Moreover, the secretion of DA was tested by enzyme-linked immunosorbent assay (ELISA) and high-performance liquid chromatography (HPLC). Chromosome G-banding analysis was used to detect the genetic stability of DA-BMSCs. Subsequently, the DA-BMSCs were stereotactically transplanted into the right medial forebrain bundle (MFB) of Parkinson's rat models to detect their survival and differentiation in the intracerebral microenvironment of PD rats. Apomorphine (APO)-induced rotation test was used to detect the improvement of motor dysfunction in PD rat models with cell transplantation. The TH, DDC and GCH1 were expressed stably and efficiently in the DA-BMSCs cell line, but not expressed in the normal rat BMSCs. The concentration of DA in the cell culture supernatant of the triple transgenic group (DA-BMSCs) and the LV-TH group was extremely significantly higher than that of the standard BMSCs control group (P < 0.000 1). After passage, DA-BMSCs stably produced DA. Karyotype G-banding analysis showed that the vast majority of DA-BMSCs maintained normal diploid karyotypes (94.5%). Moreover, after 4 weeks of transplantation into the brain of PD rats, DA-BMSCs significantly improved the movement disorder of PD rat models, survived in a large amount in the brain microenvironment, differentiated into TH-positive and GFAP-positive cells, and upregulated the DA level in the injured area of the brain. The triple-transgenic DA-BMSCs cell line that stably produced DA, survived in large numbers, and differentiated in the rat brain was successfully established, laying a foundation for the treatment of PD using engineered culture and transplantation of DA-BMSCs.
