We have previously demonstrated that fucoidan, an antithrombotic polysaccharide, promotes the formation of new blood vessels in a mouse model of hindlimb ischemia. We examined the effect of fucoidan on the capacity of peripheral blood monocytes to adhere and migrate. Monocytes negatively isolated with magnetic beads from peripheral blood of healthy donors were treated with fucoidan. Fucoidan induced a 1.5-fold increase in monocyte adhesion to gelatin (p &lt; 0.05) and a five-fold increase in chemotaxis in Boyden chambers (p &lt; 0.05). Fucoidan also enhanced migration 2.5-fold in a transmigration assay (p &lt; 0.05). MMP9 activity in monocyte supernatants was significantly enhanced by fucoidan (p &lt; 0.05). Finally, Western blot analysis of  fucoidan-treated monocytes showed upregulation of ERK\/p38 phosphorylation. Inhibition of ERK\/p38 phosphorylation abrogated fucoidan enhancement of migration (p &lt; 0.01). Fucoidan displays striking biological effects, notably promoting monocyte adhesion and migration. These effects involve the ERK and p38 pathways, and increased MMP9 activity. Fucoidan could improve critical limb ischemia by promoting monocyte recruitment.<\/jats:p>","DOI":"10.3390\/md13074156","type":"journal-article","created":{"date-parts":[[2015,6,30]],"date-time":"2015-06-30T11:40:13Z","timestamp":1435664413000},"page":"4156-4170","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Fucoidan Stimulates Monocyte Migration via ERK\/p38 Signaling Pathways and MMP9 Secretion"],"prefix":"10.3390","volume":"13","author":[{"given":"Elene","family":"Sapharikas","sequence":"first","affiliation":[{"name":"Inserm UMR_S 1140, Facult\u00e9 de Pharmacie, Universit\u00e9 Paris Descartes, Sorbonne Paris Cit\u00e9,  4 Avenue de l'observatoire Paris 75006, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Lokajczyk","sequence":"additional","affiliation":[{"name":"Inserm UMR_S 1140, Facult\u00e9 de Pharmacie, Universit\u00e9 Paris Descartes, Sorbonne Paris Cit\u00e9,  4 Avenue de l'observatoire Paris 75006, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anne-Marie","family":"Fischer","sequence":"additional","affiliation":[{"name":"Inserm UMR-S 970, AP-HP, H\u00f4pital Europ\u00e9en Georges Pompidou, 20 rue Leblanc Paris 75015, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Catherine","family":"Boisson-Vidal","sequence":"additional","affiliation":[{"name":"Inserm UMR_S 1140, Facult\u00e9 de Pharmacie, Universit\u00e9 Paris Descartes, Sorbonne Paris Cit\u00e9,  4 Avenue de l'observatoire Paris 75006, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2015,6,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"688","DOI":"10.1161\/CIRCULATIONAHA.105.593442","article-title":"Peripheral arterial disease: Morbidity and mortality implications","volume":"114","author":"Golomb","year":"2006","journal-title":"Circulation"},{"key":"ref_2","first-page":"81","article-title":"TASC II Working Group Inter-society consensus for the management of peripheral arterial disease","volume":"26","author":"Norgren","year":"2007","journal-title":"Int.
