Although fibroblasts contribute to the construction of ECM structure in SD, some studies have reported that mast cell degranulation causes the disruption of ECM in early SD lesions. Lagerstroemia indica flower (LIF) has traditionally been used in India as a diuretic. However, little is known about the effect and molecular action of Lagerstroemia indica flower extract (LIFE) on alleviating SD. This study evaluated the effects of LIFE on mast cell degranulation and the synthesis of ECM components in fibroblasts. LIFE inhibits the adhesion of rat basophilic leukemia (RBL) cells, RBL-2H3 on fibronectin (FN) and the expression of integrin, a receptor for FN, thereby reducing focal adhesion kinase (FAK) phosphorylation. In addition, LIFE attenuated the allergen-induced granules and cytokine interleukin 3 (IL-3) through the adhesion with FN. Moreover, the conditioned medium (CM) of activated mast cells decreases the synthesis of ECM components, and LIFE restores the abnormal expressions induced by activated mast cells. These results demonstrate that LIFE suppresses FN-induced mast cell activation and promotes the synthesis of ECM components in fibroblast, which indicates that LIFE may be a useful cosmetic agent for SD treatment.<\/jats:p>","DOI":"10.3390\/molecules27041274","type":"journal-article","created":{"date-parts":[[2022,2,14]],"date-time":"2022-02-14T20:58:03Z","timestamp":1644872283000},"page":"1274","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["The Alleviating Effect of Lagerstroemia indica Flower Extract on Stretch Marks through Regulation of Mast Cells"],"prefix":"10.3390","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7302-2743","authenticated-orcid":false,"given":"Miji","family":"Yeom","sequence":"first","affiliation":[{"name":"Biospectrum, Life Science Institute, Yongin-si 16827, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hyanggi","family":"Ji","sequence":"additional","affiliation":[{"name":"Biospectrum, Life Science Institute, Yongin-si 16827, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jongheon","family":"Shin","sequence":"additional","affiliation":[{"name":"Biospectrum, Life Science Institute, Yongin-si 16827, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eunae","family":"Cho","sequence":"additional","affiliation":[{"name":"Biospectrum, Life Science Institute, Yongin-si 16827, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"De-Hun","family":"Ryu","sequence":"additional","affiliation":[{"name":"Biospectrum, Life Science Institute, Yongin-si 16827, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Deokhoon","family":"Park","sequence":"additional","affiliation":[{"name":"Biospectrum, Life Science Institute, Yongin-si 16827, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5594-4645","authenticated-orcid":false,"given":"Eunsun","family":"Jung","sequence":"additional","affiliation":[{"name":"Biospectrum, Life Science Institute, Yongin-si 16827, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,2,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"527","DOI":"10.1111\/bjd.12681","article-title":"Striae Distensae: A Comprehensive Review and Evidence-Based Evaluation of Prophylaxis and Treatment","volume":"170","author":"Gilmore","year":"2014","journal-title":"Br.
