Ukuvela Kwezinto Eziphilayo
Izithako zezitshalo sezilokhu zisetshenziswa kabanzi ekwakhiweni kwezimonyo, zibalulekile ngenxa yamakhemikhali azo asebenzayo ngokwemvelo kanye nokukhanga okukhulu kwabathengi. Kodwa-ke, njengoba ukusungula izinto ezintsha zokunakekelwa kwesikhumba kugxila kakhulu ekusebenzeni kahle okuphezulu, izinhlelo zokulethwa ezithuthukisiwe, kanye nokunemba kokwakheka, izingcezu zezitshalo zendabuko seziqala ukwembula imikhawulo ethile - ikakhulukazi maqondana nokuzinza, ukuhambisana, kanye nokutholakala kwezinto eziphilayo.
Lolu shintsho embonini luqhuba intshisekelo ekhulayo kuma-Plant Cell-Derived Exosomes (Plant Cell-Derived EVs/PDNVs), ipulatifomu ye-biotechnology esafufusa ehlanganisa isayensi yezitshalo nemiqondo yokulethwa esebenzayo yesizukulwane esilandelayo.
Okungaphezu Kokuqoqwa Kwezitshalo Ezivamile
Ngokungafani nokukhishwa kwezitshalo okuvamile okutholakala ngezinqubo zokukhipha i-solvent noma ngokomzimba, ama-exosome atholakala kumaseli ezitshalo angama-vesicles angaphandle asayizi omncane akhiqizwa ngezinhlelo zokukhulisa amaseli ezitshalo ezilawulwayo.
Isakhiwo sabo se-lipid bilayer membrane sisiza ukuhlanganisa nokuvikela ama-molecule asebenzayo, okuhlanganisa ama-lipid, amaprotheni, ama-polyphenols, kanye nama-signal compounds. Lesi sakhiwo se-vesicular sisiza ukuthuthukisa ukuzinza kwezithako ezisebenzayo ezizwelayo ngenkathi sigcina ubuqotho bazo kulo lonke ukuthuthukiswa nokusetshenziswa kokwakheka.
Indlela Yokuletha Ehlakaniphile
Ukusebenza kahle kokulethwa kungenye indawo edonsela ukunaka okukhulu. Izithako zezitshalo zendabuko zivame ukuba namaphrofayili okwakheka ayinkimbinkimbi futhi zingase zibhekane nezinselele ezihlobene nokungena kwesikhumba kanye nokusetshenziswa okusebenzayo.
Ama-exosome atholakala kumaseli ezitshalo, ngokuvamile asukela ku-30-200 nm, anikeza uhlelo lokulethwa olucwengekile kakhulu olunamandla okuthuthukisa ukusebenzisana nesithiyo sesikhumba nokuthuthukisa ukutholakala kwezinto ezisebenzayo. Njengoba imboni iqhubeka nokuhlola ubuchwepheshe bokulethwa obuqondiwe nobusebenza kahle, ama-vesicle ezitshalo ezincane aqala ukuba yindawo ebalulekile yocwaningo lobuhle kanye nokuthuthukiswa kokwakheka.
Ukuvumelana Nge-Biotechnology
Ukungaguquguquki kokukhiqiza nakho kuvela njengenzuzo eyinhloko. Izithako zezitshalo ezivamile zivame ukuthonywa ukushintshashintsha kwezinkathi, izimo zezulu, kanye nokutholwa kwezolimo, okungaholela ekuhlukeni kweqembu ngalinye.
Uma kuqhathaniswa, ubuchwepheshe bokukhulisa amaseli ezitshalo buvumela izinqubo zokukhiqiza ezikwazi ukulinganiswa, ezijwayelekile, nezilawulekayo, okusiza ekufinyeleleni ikhwalithi ephindaphindwayo kanye nokusebenza okuzinzile ngenkathi kunciphisa ukuncika ezinsizeni zezolimo zendabuko.
Ikusasa Lokusungula Izinto Ezintsha Kwezitshalo
Njengoba ubuchwepheshe be-biocosmetic buqhubeka nokukhula, ama-exosome asuselwa kumaseli ezitshalo aya ngokuya ebhekwa hhayi nje njengesithako sezitshalo, kodwa njengeplatifomu entsha yokusungula izinto ezintsha zokunakekelwa kwesikhumba esizukulwaneni esilandelayo.
Ngokuhlanganisa ukusimama, ikhono lokulethwa elithuthukisiwe, kanye nokusebenza kahle kwezinto eziphilayo, ama-exosome asuselwa kumaseli ezitshalo amelela ukuhlangana okukhulayo kwesayensi yezitshalo, ubuchwepheshe bezinto eziphilayo, kanye nomklamo wokwakheka kwezimonyo wesimanje.
