J Pers Med 2024; 14:554. [PMID: 38929774 PMCID: PMC11204686 DOI: 10.3390/jpm14060554] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2024] [Revised: 05/17/2024] [Accepted: 05/21/2024] [Indexed: 06/28/2024] Open
Abstract
BACKGROUND In reconstructive surgery, local flaps might develop tissue necrosis or partial flap loss especially after previous irradiation, which may be necessary in many tumor entities. The application of stem cells seems promising to improve flap perfusion and might be a possible solution to optimize flap survival. METHODS Twenty rats received harvesting of bilateral random pattern fasciocutaneous flaps. The right flaps received 20 Gy ionizing radiation 4 weeks prior to the surgery, while the left flaps served as the non-irradiated control. After flap harvest, four different stem cell mixtures (5 × 106 ASC, ASC-HUVEC, MSC, MSC-HUVEC) were applied under both right and left flaps using 1 mL fibrin glue as the delivery vehicle. Flap size and its necrotic area were examined clinically. Two weeks after the surgery, HE staining and immunohistochemical staining for CD68 and ERG, as well as PCR analysis (Interleukin 6, HIF-1α and VEGF), were performed. RESULTS Application of ASCs, ASCs-HUVECs and MSCs resulted in a lower number of CD68-stained cells compared to the no cell group. The expression of Hif1α was higher in the ASC group compared to those in the MSC and previously treated no cell groups. Treatment with MSCs and MSCs-HUVECs prevented shrinking of the flaps in this series. CONCLUSION Application of ASCs, MSCs and ASCs-HUVECs was shown to have an antiinflammatory effect. Treatment with MSCs and MSCs-HUVECs can prevent early shrinking of the flaps.

Abstract
Radiotherapy causes DNA damage by direct ionization and indirect generation of reactive oxygen species (ROS) thereby destroying cancer cells. However, ionizing radiation (IR) unexpectedly elicits metastasis and invasion of cancer cells by inducing cancer stem cells' (CSCs) properties. As BMI1 is a crucial gene that causes radioresistance and an unfavorable prognosis of hepatocellular carcinoma (HCC), BMI1 inhibitor PTC-209 has been encapsulated in a ROS-responsive liposome (LP(PTC-209)) to be temporally and spatially delivered to radioresistant HCC tissue. The ROS generated during IR was not only considered to directly cause tumor cell death but also be used as a stimulator to trigger ROS-responsive drug release from LP(PTC-209). The PTC-209 released into resistant HCC tissue under radiotherapy further led to cancer stem cell (CSC) differentiation and then recovered radiosensitivity of HCC tumor. The suppression of the radioresistant performance of LP(PTC-209) has been proved on radiosensitive and radioresistant Hepa1-6 CSC tumor models, respectively. Our study clarified the relationship between radiotherapy and cancer stemness and provided insights to achieve complete suppression of radioresistant HCC tumor by inhibiting cancer stemness.

Abstract
OBJECTIVE Aim: To evaluate efficacy and safety of autologous bone marrow-derived mononuclear stem cell transplantation intrathecal in children with cerebral palsy. PATIENTS AND METHODS Materials and Methods: 35 children have levels I-V cerebral palsy aged 8-months to 8-years-old were enrolled from September (2021-2022) at Iraqi private hospital. Gross Motor Function was assessed by a pediatrician and neurologist specialist, 5 mcg/kg/day of G-CSF subcutaneous single injection daily for three consecutive days. Bone marrow harvested from posterior iliac crest under light general anesthesia. Bone marrow mononuclear cells (BMMNCs) separation was performed using density gradient centrifugation with Ficoll, the cell viability checked by propidium iodide dye in a TALI machine (Invitrogen) in average 98%. The viable BMMNCs injected intrathecal in L4-L5 over a period of 5-10 min. RESULTS Results: Males accounted for 57.14% (20/35) while female 42.86% (15/35), and main neurological symptoms included spastic disorder spastic disorder (quadriplegia 24 (68.6), tetraplegia 2 (5.7), diplegia 5 (14.28), hemiplegia4 (11.42)). Gross Motor Function Classification System and Gross Motor Function Measure-66 (GMFM-66) showed II 10 (28.58), III 11(31.42) and IV 14 (40). On mean follow-up of 3 months post-stem cell transplant improvement was observed in 80% cases. The improvement showed in gross motor function (6/8) p=0.01, and speech (2/4) p=0.04, neck holding (5/5) p=0.0003, sitting balance (4/4) p=0.04, postural tone (5/5) p=0.0003, as well as significant reduction in seizure frequency (2/3) p=0.04 and improvement in cognition (6/7) p=0.01 were observed. CONCLUSION Conclusion: Stem cell therapy for cerebral palsy shows a significant positive effect on the gross motor function, without long adverse effects.

Abstract
Stem cells have the capacity to ensure the renewal of tissues and organs. They
could be used in the future for a wide range of therapeutic purposes and are
preserved at liquid nitrogen temperature to prevent any chemical or biological
activity up to several decades before their use. We show that the cryogenized
cells accumulate damages coming from natural radiations, potentially inducing
DNA double-strand breaks (DSBs). Such DNA damage in stem cells could lead to
either mortality of the cells upon thawing or a mutation diminishing the
therapeutic potential of the treatment. Many studies show how stem cells react
to different levels of radiation; the effect of terrestrial cosmic rays being
key, it is thus also important to investigate the effect of the natural
radiation on the cryopreserved stem cell behavior over time. Our study showed
that the cryostored stem cells totally shielded from cosmic rays had less DSBs
upon long-term storage. This could have important implications on the long-term
cryostorage strategy and quality control of different cell banks.
