GATA2 deficiency causes lymphatic malformations and lymphedema. Delayed lymphatic recanalization after popliteal lymph node removal in Gata2 heterozygous (Gata2 \u00a0+\/\u2212) mice is associated with collagen accumulation in the surrounding tissue. In this study, we investigated whether extracellular matrix (ECM) alterations contribute to lymphatic recanalization by analysing subcutaneous tissue from Gata2 \u00a0+\/\u2212 and Gata2 and Gata3 double heterozygous (Gata2+\/\u2212::Gata3+\/\u2212) mice. RNA-seq analysis revealed changes in ECM-related and adhesion-associated genes in both genotypes. Histological analyses demonstrated collagen accumulation and disorganized collagen bundles in Gata2+\/\u2212::Gata3+\/\u2212 mice. Immunostaining further revealed reduced elastin fibres and decreased numbers of fibroblasts in subcutaneous tissues of Gata2+\/\u2212 and Gata2+\/\u2212::Gata3+\/\u2212 mice. These findings suggest that abnormalities in ECM organization, including altered collagen and elastin structures and reduced fibroblast populations, may underlie collagen accumulation and impaired lymphatic recanalization. Notably, Gata2+\/\u2212::Gata3+\/\u2212 mice exhibited a patchwork-like dermal phenotype reflecting features of both single mutants, possibly owing to mosaic transcriptional regulation within the GATA gene network. The microenvironmental ECM structure plays an important role in lymphatic recanalization following lymphatic injury.<\/jats:p>","DOI":"10.1093\/jb\/mvag068","type":"journal-article","created":{"date-parts":[[2026,9,29]],"date-time":"2026-09-29T11:45:52Z","timestamp":1790682352000},"source":"Crossref","is-referenced-by-count":0,"title":["Microenvironmental extracellular matrix remodelling driven by GATA2 and GATA3 deficiency impairs lymphatic recanalization"],"prefix":"10.1093","author":[{"given":"Tomomi","family":"Watanabe-Asaka","sequence":"first","affiliation":[{"name":"Division of Physiology, School of Medicine, Tohoku Medical and Pharmaceutical University , 1-15-1 Fukumuro, Miyagino-ku, Sendai 983-8536 ,","place":["Japan"]},{"name":"Department of Physiology, Tokai University School of Medicine , 143 Shimokasuya, Isehara 259-1193 ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Moyuru","family":"Hayashi","sequence":"additional","affiliation":[{"name":"Division of Physiology, School of Medicine, Tohoku Medical and Pharmaceutical University , 1-15-1 Fukumuro, Miyagino-ku, Sendai 983-8536 ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takuya","family":"Harada-Norikane","sequence":"additional","affiliation":[{"name":"Division of Physiology, School of Medicine, Tohoku Medical and Pharmaceutical University , 1-15-1 Fukumuro, Miyagino-ku, Sendai 983-8536 ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mayu","family":"Nakamura","sequence":"additional","affiliation":[{"name":"Division of Physiology, School of Medicine, Tohoku Medical and Pharmaceutical University , 1-15-1 Fukumuro, Miyagino-ku, Sendai 983-8536 ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"May","family":"Kouriki","sequence":"additional","affiliation":[{"name":"Division of Physiology, School of Medicine, Tohoku Medical and Pharmaceutical University , 1-15-1 Fukumuro, Miyagino-ku, Sendai 983-8536 ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun","family":"Takai","sequence":"additional","affiliation":[{"name":"Division of Medical Biochemistry, School of Medicine, Tohoku Medical and Pharmaceutical University , 1-15-1 Fukumuro, Miyagino-ku, Sendai 983-8536 ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0354-6821","authenticated-orcid":false,"given":"Satoshi","family":"Uemura","sequence":"additional","affiliation":[{"name":"Division of Medical Biochemistry, School of Medicine, Tohoku Medical and Pharmaceutical University , 1-15-1 Fukumuro, Miyagino-ku, Sendai 983-8536 ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takuo","family":"Hirose","sequence":"additional","affiliation":[{"name":"Division of Physiology, School of Medicine, Tohoku Medical and Pharmaceutical University , 1-15-1 Fukumuro, Miyagino-ku, Sendai 983-8536 ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2011-2603","authenticated-orcid":false,"given":"Yoshiko","family":"Kawai","sequence":"additional","affiliation":[{"name":"Division of Physiology, School of Medicine, Tohoku Medical and Pharmaceutical University , 1-15-1 Fukumuro, Miyagino-ku, Sendai 983-8536 ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2026,9,30]]},"reference":[{"key":"2026101519212926900_ref1","first-page":"4011","article-title":"DNA-binding specificities of the GATA transcription factor family","volume":"13","author":"Ko","year":"1993","journal-title":"Mol.
