Cell-based treatment of cerebral palsy: still a long way ahead

BACKGROUND

Cerebral palsy (CP) is a permanent neurodevelopmental disorder with considerable global disability. Various rehabilitation strategies are currently available. However, none represents a convincing curative result. Cellular therapy recently holds much promise as an alternative strategy to repair neurologic defects.

METHOD

In this narrative review, a comprehensive search of the MEDLINE and ClinicalTrials.gov was made, using the terms: "cell therapy" and "cerebral palsy", including published and registered clinical studies, respectively.

RESULTS

The early effects of these studies demonstrated that using cell therapy in CP patients is safe and improves the deficits for a variable duration. Despite such hopeful early bird results, the long-term outcomes are not conclusive.

CONCLUSIONS

Due to the heterogeneous nature of CP, personal factors seem essential to consider. Cell dosage, routes of administration, and repeated dosing are pivotal to establish optimal personalized treatments. Future clinical trials should consider employing other cell types, specific cell modifications before administration, and cell-free platforms.

Communication barriers between basic scientists and clinicians in regenerative medicine: A qualitative study from Iran

RATIONALE, AIMS, AND OBJECTIVES

Cell-based therapeutics are among the latest advances in health care technologies. The rapid evolution of stem cell science in Iran has necessitated the application of scientific achievements in clinical settings. However, various issues hindered their translation, in particular, impediments in the interactions of basic stem cell scientists and clinicians. We highlighted the impediments in the interactions of stem cell scientists and physicians involved in the opinion of professionals from both groups.

METHOD

This qualitative research was conducted with thematic analysis, performed by purposive sampling. Thirty-two distinguished stem cell scientists and clinicians were interviewed to identify their perspectives on this matter. MAXQDA 2018 was used to classify the axial codes based on factors related to communications inefficiencies. The analysis of coded data recognized 18 subthemes and six major themes.

RESULTS

Central themes include different registers of the two parties, counterproductive clusters hampered networking, external communication barriers, the competition to access resources, leadership conflicts, and the dissatisfaction of stakeholders with their share.

CONCLUSIONS

Most of the impediments were seemingly global, for example, the incoherent medical and basic science educational systems, the vulnerable career path of physician-scientists, and an increasing tendency towards overspecialization. However, some local specific issues were also described, for example, limited funding opportunities and the negative impacts of the division of medical education from the ministry of science, research, and technology in Iran. Proposed interventions include the reinforcement of physician-scientist programs, designing a distributed leadership model, and bringing back the scientific integrity to higher education in Iran.
