A Bibliometric Analysis of the Spatial Transcriptomics Literature from 2006 to 2023

Tracking the evolution, global trends, and research hotspots in the rapidly growing field of spatial transcriptomics

Spatial Biology Bibliometrics Research Trends

Introduction

Spatial transcriptomics has emerged as a revolutionary technology that enables researchers to profile gene expression within the context of tissue architecture 1 . This approach overcomes the limitation of traditional single-cell RNA sequencing, which loses crucial spatial information during tissue dissociation 2 .

The field of spatial transcriptomics has experienced exponential growth since its inception, transforming our understanding of tissue organization and function in both health and disease 3 .

Bibliometric analysis provides a quantitative approach to examine the development of research fields, identify emerging trends, and map scientific collaborations 4 . This study presents a comprehensive bibliometric analysis of the spatial transcriptomics literature from 2006 to 2023, capturing the evolution of this rapidly advancing field.

Exponential Growth

Annual publications in spatial transcriptomics increased from fewer than 100 before 2019 to 630 by 2023 1 .

Discussion

The bibliometric analysis reveals several important trends in the spatial transcriptomics literature:

Exponential Growth Phase

The field has entered an exponential growth phase since 2019, driven by technological advancements and commercial platform availability 1 5 . This pattern is characteristic of emerging scientific fields with high potential for impact.

Global Research Landscape

The United States maintains leadership in spatial transcriptomics research, but China has shown remarkable growth in recent years 1 . European countries, particularly the UK, Germany, and Sweden, also contribute significantly to the field.

Collaboration Patterns

International collaborations account for over one-third of publications, indicating the global nature of spatial biology research 1 . Collaborative networks often form around methodological development and large-scale atlas projects.

Research Themes

Keyword analysis reveals strong connections between spatial transcriptomics and cancer research, neuroscience, and developmental biology 1 . Methodological papers focusing on resolution and technology improvement represent another major theme.

The convergence of spatial transcriptomics with other omics technologies and artificial intelligence represents the next frontier in spatial biology research 6 7 .

Limitations and Future Directions

This bibliometric analysis has several limitations, including database coverage constraints and the challenge of accurately categorizing interdisciplinary research. Future studies could benefit from:
